My wife and I spent a great few days at the double tree. Our room was really nice and incredibly spacious - we had a large 2-bedroom just for the two of us. The beach is great in this part of town much better than in south beach - less crowded and the sea is so close.
South Beach is not far - took us 20 mns by car every time we went out. The staff was very friendly in particular the valet staff which was efficient and never made us wait. The location enabled me to go for great runs toward the south of the hotel. The hotel is not brand new but in decent shape.
