This is a really nice hotel perfect if you're travelling on a mid range budget. For a tourist it's a nice safe 15 min walk from the hotel down 14th street to the national mall. Then all the memorials and Smithsonian's are within 15 mins max. If your tired at the end of the day a cab will cost $10 back to the hotel.
The Hotel rooms are very spacious, nicely apportioned and clean. Only negative comment was the pillows were quite large and hard.
The lounge and restaurant downstairs is very spacious and pleasant with good drinks and meals.
Overall, we went to Washington to do the tourist thing and this hotel was ideal. Would definitely return.
