We stayed here on points. Charleston is an expensive town but it is a must to stay in the historic district and be in walking distance of everywhere.
We recommend renting bikes to really see ALL of Charleston. There are two bike rental shops close to the hotel. The on site lower level parking ($16 a day) is nice, especially since it rained when we were leaving. All of the staff were exceptionally friendly which really is not that uncommon in Charleston.
They only negative we had was that the elevators are on one side of the building and our room was at the farthest point on the other side. Of course, maybe that's why We had such a quiet stay.
The room was spotless. Bed was very comfortable. We would definitely stay here again.
