Good location, friendly staff and good room size
Stayed only 2 nights in July 2012 with friends and we had a good time here. 
Location in quiet, near Dupont Circle. We had a car so it was easy to drive aroud the city. Parking was always full so we had to park in the street.
The room was big (Grand Suite) on the 5th floor with some view at the back. Nice kitchen, big king bed, free wifi, flat TV. Only thing was that the bathroom was small for such a big room.
The frontdesk staff was very helpful and attentive. Check-out process was a bit too long.
We had breakfast once at the hotel but it was expensive and without special food. Lack of choice. Even the espresso coffee was charged extra and the staff wasn't nice there. Avoid!
I would stay maybe again here if I had no other choice in DC for the same price and a good location.
