Stay away from the Wardman Park tower
I was at the Marriott Wardman Park for a conference. I deliberately chose a room in the Wardman Tower when I booked because it sounded more interesting than the generic Marriott part of the hotel. In theory, that's true, but the Wardman Tower is very dowdy and in desperate need of renovation. The bathroom had been updated and was very clean, and the room itself was large. However, all of the furniture was quite beat up, the carpets were stained and the upholstery and draperies were faded and stained. The woodwork must have had 100 layers of old paint. The elevators are old, creaky and slow. In addition, if you're here for a conference, the Wardman tower is quite inconvenient...a long hike to the rest of the hotel, meeting rooms and downstairs exhibition space. This is a less-than-ideal location in DC...far from monuments, etc., but if you must stay here for a conference, definitely opt for one of the newer rooms.
