Liked: Cleanliness, staff & service, property conditions & facilities
The room was decent size, the bed pillows were very small, the bath towels were small and thin and the sink faucet didn’t work well the water dripped very light. The landscaping was very nice with lots of palm trees and paradise type flowers and had a very large beautiful pool. The comp breakfast was somewhat small and didn’t have an attendant in there so there were dirty tables. The place overall wasn’t terrible but I would probably stay somewhere if ever in the area again
