Reviewer Type: Family With Children
Travel Purpose: leisure
Positive: I've stayed here before and the room was so cute plus we had a balcony overlooking the pool/beach on the adult side. This time we stayed in a 2 bedroom apartment. It was comfortable, had what we needed as far as fridge, bathrooms, etc. I like that the parking, is attached. The space is cute and just really enjoy the atmosphere of the resort
Negative: the lighting in the room wasn't great and could be upgraded. Other upgrades needed are plugs or furniture with usb ports for the multiple electronics people have now. I like that the parking is attached, however, it rained while we were there and had to find alternate routes due to flooding in the pathway when walking to the lobby/restaurant.
Summary: 2nd time stay and will again
