Isla Bella Beach Resort & Spa generally receives positive feedback, highlighted by stunning property views, friendly staff, and excellent food. However, recurring concerns include inconsistent beach cleanliness, unexpected fees, and occasional issues with room maintenance like malfunctioning AC and outdated amenities. Some guests find the resort’s pricing doesn’t align with the overall experience.
Before I get started this hotel was amazing the staff and the views were incredible! The reason for the three star review however was due to having to call the front desk multiple times because outside our room near the outdoor chess board there was kids screaming, running around and hitting each other with the plastic chess pieces at 12:30 at night keeping the entire side of the hotel we were on awake with all the noise. I had to call the desk twice and it took almost an hour for them to finally find their parents and quiet them down, it’s not the hotels fault however for misbehaving children that falls to their parents, if your looking for a more quiet adult centric experience I would look elsewhere but if you have kids this is a great place to stay as they seem to be more family oriented.
Very disappointing experience, especially for a hotel that advertises itself as “pet friendly.” The hotel charges $100 PER NIGHT for a dog, yet dogs are not allowed in the common areas and also cannot be left alone in the room. So where exactly is your dog supposed to be? Charging such a significant nightly pet fee while having these restrictions is extremely misleading. This is definitely not what I would consider a truly pet-friendly hotel. Unfortunately, the poor experience goes beyond the pet policy. The rooms are in need of maintenance and attention to detail, and even something as basic as bottled water was not available in the room or fridge. We were also celebrating a birthday and brought a bottle of champagne. We simply asked for champagne glasses, and the hotel was only able to provide three glasses. For a hotel charging these rates, it was surprising that such a basic request could not be accommodated. Overall, the service and attention to guests were extremely poor in almost every aspect of our stay. Between the misleading “pet-friendly” policy, the $100 nightly pet charge, the condition of the rooms, lack of basic amenities, and poor service, the experience did not come close to meeting expectations. If you are traveling with a dog, I would absolutely recommend looking elsewhere. There are genuinely pet-friendly hotels that actually make their guests and their pets feel welcome. On top of that my sister in law cut her hand accidentally at the beach,, and they didnt even have a proper first aid kit to assist her.. we has to get everything at CVS,, just tape they had available and after 3 trips the lady made to i dont know where to get it… just tape ??? Really Not to mention that if you ask for some decoration for a Birthday, they will charge you $95 per night for 6 miserables Balloons that will be a one time decoration, but they charge like they did it every day..
Absolutely exceptional stay at Isla Bella Beach Resort & Spa. The property is beautiful, exceptionally well maintained, and the entire experience exceeded our expectations. The staff were genuinely friendly, attentive, and accommodating throughout our stay, which made a great resort feel even more special. The food was excellent as well—fresh, flavorful, and consistently enjoyable. Between the beautiful surroundings, comfortable accommodations, outstanding service, and quality dining, Isla Bella delivered exactly the relaxing Florida Keys experience we were hoping for. We thoroughly enjoyed our time here and would absolutely return. Highly recommend Isla Bella to anyone looking for a beautiful, relaxing resort with excellent service and food. Five stars across the board.
I had a wonderful experience staying at this hotel. Everything was clean, comfortable, and well organized, but what really stood out was the exceptional customer service. A huge thank you to Aruzhan at the front desk for making check-in so easy and welcoming. She was incredibly friendly, professional, and made us feel right at home from the very beginning. I also want to recognize Pedro from the restaurant for his outstanding service. He was attentive, courteous, and always made sure we had everything we needed. His positive attitude and attention to detail truly made every meal a pleasure. The hospitality shown by Aruzhan and Pedro made this stay unforgettable. I would gladly recommend this hotel to anyone looking for excellent service, and I can’t wait to come back.
We had such a wonderful stay at Isla Bella Resort! The property is absolutely beautiful, very well maintained, and has so many great amenities to enjoy. Everything from the pools to the overall atmosphere made it the perfect place to relax. The customer service was excellent throughout our stay. Everyone we interacted with was friendly, welcoming, and genuinely made us feel taken care of. The service was top-notch and really made the experience even better. We truly enjoyed our time here and can't wait to come back. Highly recommend this resort if you're looking for a relaxing getaway in the Keys!
My husband and I visited during the first week of June 2026 to celebrate my 41st birthday, and we had a wonderful experience overall. The rooms were beautiful, clean, and very comfortable. A special thank you to Allison at the Maihia Restaurant. She was incredibly kind, attentive, and provided outstanding customer service throughout our stay. We were there for four days, and she remembered both my birthday and my coffee order, which made me feel truly valued as a guest. Her thoughtfulness and warm personality made my experience even more enjoyable. The only downside was the beach. Unfortunately, the water was not as clean as I had hoped. However, everything else about the property was gorgeous and gave me the feeling of being on a tropical island. Despite the beach conditions, I thoroughly enjoyed my stay and would definitely return in the future.?
Isla Bella was a very nice resort with quality rooms and a nice walk out deck to the sand area. The greeting was wonderful, they offer a nice taste of champagne/wine while you wait, but we didn't have to wait even long enough to drink it. I found all the restaurants to be top quality, sure they take their time, but remember you are supposed to be on island time and enjoying the ambiance! The sushi lobster/unagi roll was great and the cucumber salad was really good at the sushi place. The beach bar bartender was really nice and turned on the hockey playoff game for me. The queso fries and tempura spicy sauce jumbo shrimp was really good. Mahina was a wonderful experience deserving of being the best on the island. Wagyu ravioli, beef short ribs, whole fried snapper, shrimp skewers - all good no dish was left lacking that we tried. The only eatery i didnt try was the burger shack by the main resort pool. The views are wonderful from everywhere and the room we had had a back(front?) deck walkout to the sandy area. Supports disabled people well, there are a few parking spots and a elevator if needed. The staff was very nice from check-in to checkout. I asked for a microwave and 5 towels and they were at my room in no less than 30 minutes. The main resort pool was very nice, i didnt get a chance to swim in the other pools but they have many and even an adult only pool. We spent most of our time around the various vast key islands so we didnt get to fully indulge in everything the place had to offer but overall i would recommend it to anyone who likes top notch resort life. I gave five star since there isnt really mid ratings, this is close to 4.75 stars, the only issue being the resort beach wasn't really swimmable at the time we visited.
Top notch rooms with nice views. Excellent meals at Marina Restaurant. Lovely front desk staff. The grounds are limited: there's a tiny beach, which we didn't utilize due to jelly fish & man of war warning signs (we appreciated the warning); small pools with nice lounge chairs & umbrellas and old, small towels; no paths to go for a long walk. Everything cost extra & is expensive: all meals ($50+ entrees, $16 drinks), snacks ($8 ice cream), parking ($30/day), spa ($300 massage), and snorkeling gear. The bicycles and water were complimentary. The place felt really corporate & inauthentic. We had a relaxing time here, but honestly, there's a lot better out there for a lot less cost.
I cannot recommend this place enough. The rooms were gorgeous, the view was amazing, and the sunsets even better. Staff was amazing (shout out to Karl, Conner, and Annie). I have been all over the world and stayed at a lot of resorts and this is one of the only ones I would return to without question. The one negative thing I will say is the food really left something to be desired, especially the sushi. Prices here were at least 50% higher than everywhere else we went and the outside food was dramatically better and had more food. All in all though 9 / 10.
Really enjoyed our time here. The property is really clean, well landscaped and cleverly designed with several pools and dining venues conveniently placed throughout the property so that you’re never too far from a pool or a glass of wine. Very kid friendly but not to the point where kids run the place. Staff is very professional and helpful. Rooms are clean, spacious and tastefully decorated. Highly recommended!
