As others have mention, the Coral Gables location can't be beat. The hotel is a stone's throw from the restaurants and shopping of the Miracle Mile and not far from several major office buildings.
The property itself is just OK. It occupies several floors of an office building and there is a long walk to some of the rooms. The hotel is going through some renovations and a few of the rooms (esp. the Westin Workout rooms) are nice, but many could use a serious update.
Service has been pretty solid on the basics (room service, getting the car out, etc) but the concierge has not impressed and the hotel doesn't really go above and beyond...
Overall, a solid hotel for the area but definitely not worth a special trip.
