Quite a nice place to stay in Dupont Circle / Kalorama
I was part of an interview committee which met candidates in D.C., and the search firm suggested this hotel. Very comfortable, downright luxurious! I had a bedroom and a little office area off the bedroom -- with a view of Connecticut Street.
I would definitely stay here again if the neighborhood were convenient for a goal I had in D.C.
The front desk was very helpful.
I'm always annoyed that places this nice charge separately for wifi. Roll it in, people! 
The only other negative comment to make is that the restaurant is currently closed for renovation -- but they still advertise the space (and it's complimentary wifi!) in the elevators.
