Hotel was decent but was definitely not a 5 star hotel.upon arrival no door man around to help with luggage. In fact throughout our 3 day stay there was never any staff at the front entry way! We had 4 outlets all near the bed that didn’t work. They sent someone to check it out immediately but they were never fixed. Food was decent and location excellent for seeing all the attractions in DC.

Great location. Housekeeping was not great. Each day the room was cleaned in the late afternoon only after requesting service at the front desk.
