The second bedroom and the upstairs bathroom are definitely NOT big enough for adults. My grown kids called it the Harry Potter bathroom and bedroom. The air conditioning is one unit upstairs in the Harry Potter bedroom and one in the downstairs bedroom. The air conditioner in the downstairs bedroom is so loud it sounds like a truck revving in the bedroom. The curtains in the downstairs bedroom do not keep light out so it is very bright with lights shining in the window. It is an ok place but not as expected and no balcony by the way. On the upside, it has a nice kitchen and family room area. They have beach chairs, a cooler and some beach towels which is nice. It is not too far from the beach although not as close as expected. It was very easy to check-in.
