Review summary
Based on recent reviews
Powered by AI
Isla Bella Beach Resort & Spa offers spacious and clean rooms, some with ocean views from their balconies and direct access to the pools, ensuring a comfortable stay. The resort boasts meticulously maintained grounds, including precisely cut foliage along the entrance and raked sand around the five pools, plus a burger joint for convenient lunches. While most find the property exceptional, some guests have mentioned that the beach is brown and not ideal. Guests can also enjoy the on-site marina for fishing and snuba, along with various lawn activities, restaurants, bars and a market offering excursions, beverages, and food.

Underwhelming Stay Despite the Scenery

beautiful surroundingsbrown sandslow service
The resort location provided beautiful surroundings that were nice to look at.
I encountered slow service at the Mahina restaurant. I only got one drink during a 2.5-hour dinner. The beach was also disappointing because the sand looked brown. I would not return to this resort.

Mixed feelings about my stay

nice combinationinconsistent serverscold breakfast
The location offers a nice combination of pools and a beach.
I found the breakfast service disorganized. Servers were inconsistent and the food took an exceedingly long time. The breakfast was cold when it arrived (very annoying). I even had to ask for coffee.

the resort has multiple pools, including an adult-only option, providing varied swimming experiences. beach towels are conveniently available at all pool areas. each pool is also equipped with chairs and umbrellas to provide comfort and relaxation.
Service
8/10
the staff was generally helpful, ensuring guests had what they needed. though mostly efficient, the poolside service sometimes experienced minor delays. this occasionally meant waiting slightly longer for drinks or assistance during peak hours.
