The house was incredible! Beautiful views, and furnishings. Only drawback was the beach. Couldn’t really access the water which was very disappointing. That’s the only thing that would keep me from renting the house again.

The house was very clean but needed maintenance done. Some bathrooms were very small Biggest disappointment was the beach. We rented this location to have a beach and you could not even get in the water due to the knee high deep muck. Wasted money on kayaks and paddle boards and we couldn't even get to use them. The outside area was beautiful and enjoyed the pool Kitchen cabinets should be labeled to make it easier to find things Being off the main road you also hear traffic Give this house 6.5/10

Great place, nice location on the beach . It was near a lot of great things to do, from fishing, to great restaurants. We did have some minor issues with some things working at the house. It did need some repairs and maintenance, but nothing to major.

Amazing home and property

Disappointed with the amount of broken items in the home for the price. Elevator did not work. Window broken, sink and fridge leaks. Floors were extremely slippery when wet inside and near pool.

Beautiful but not functional!

At first glance the oohh and awwwes. Then you realize the master bedroom will never be dark you will be up when the sun comes up, the kitchen cabinets are and absolute pain to stay open and are so uniformed you forget am I opening the diswaher or a cabinet. same with the sliding and swinging white doors. lol everyone found their closet on the 3 day and decided they should come with a straight jacket. bathroom down stairs is beautiful but the drain doesn't work so we had standing water in there for 3 more days. Pool deck gorgeous but if you didn't walk around with a squeegee you were going to fall. oh and the beach its so shallow for 200 to 300 feet depending on high tide low tide, We got beach itch. ( its snail larvae laid from being in that water.. wo we brought home more than memories. and so much of the house was in crappy workman ship or needs repair PS the upstairs balcony will kill ya if you , first the glass table I have a mark for each time I passed by it, I hit it and then the mad wasp nest in the opposite corner, basically states your not coming out here during the day, unless its raining then you will slip on this high gloss floor. And all the balls and no way to air them up. :(
