Isla Bella Beach Resort & Spa

10/10 Excellent
"Rooms were very well kept. Clean, full of towels, shower worked well. Overall rooms were great. Smaller pools were a little warm but it was September. Large pool was fantastic. Eric kept the cold ones coming and was very friendly. Grounds were very clean and everyone that worked there was very helpful. Overall experience was a 10."
