Good hotel but not my favorite part of town
The reason my wife and I stayed at this hotel was that a conference she attended was held there. The conference rate for the room was good for Washington at the time of year, but might seem pricey to many. We have lived in Washington in the past and know the city pretty well, but don't usually stay in this part of town when we visit. 
Our overall experience was very good. There were some pluses and minuses to the hotel and location:
PLUSES: friendly, helpful staff; generous-sized room and bathroom; recently refreshed decor; comfortable bed and pillows; very nice breakfast buffet; views of the Capitol (depending in room location); close to Union Station shopping, food, metro and buses, also plenty of cabs nearby; easy walk to Capitol Hill, the National Building Museum, Eastern Market and the Mall; around the corner from The Dubliner in one direction and Bistro Bis in the other.
MINUSES: kind of a soulless immediate neighborhood; no in-room safe or mini-bar; half a block from the fire station -- light sleepers beware; a short walk from a major homeless shelter. The short walk to the DC courts could be either positive or negative depending on your situation.
Definitely a place we would stay again to attend a conference at the hotel, but probably not if we were coming to Washington on other business or as tourists. That's no fault of the hotel or its very pleasant staff, we usually prefer to stay in other parts of DC.
