Friendly and professional staff. Room was very clean.. The suite I stayed in had beautiful Ugg decor, and it had everything you'll need for a comfortable stay; micro, cook top & oven, kerig & regular coffee maker, even washer and drier, etc. There's plenty of places to eat, drink & party at walking distance on the boardwalk.. Valet parking is a must, hard to find regular parking, valet service was elite.

The hotel is clean. The staff will greet you but not immediately. The rooms are ok but the beds are small and everything is built for shorter stature people. I am average and the beds and toilet are short! TV's are older. Everything is average and ok.
