I recently stayed at the TownePlace Dulles while attending a conference in Reston. I chose this hotel for the low rate and the ability to earn Marriott points. The hotel is wonderful. It is relatively new and in great shape. I stayed in a studio suite. The bed was wonderful with the new Marriott linens and pillows. Full kitchen was nice. Bathroom was spacious and clean. Hotel was quiet and parking was plentiful and well lit.
Hotel location was good. It's off of VA 28 about a mile north of Dulles Airport. It is very convenient to Reston and Herndon via Old Ox Road. No need to use the Dulles Toll Road and sit in the traffic. Overall this is a great place and I'd stay here again in a heartbeat.
