I stayed here for one night in January and was very pleased. The front desk was very helpful and answered all my questions. The room was very clean and pretty good size ( I had two queen beds). Bathroom was clean and also a fine size. The sitting / kitchen area were very large and left plenty of room for bags and such.
The brekafast area was very large with numerous tables and chairs. The pictures on TA do a very job of showing the property. There is a pool table in the lobby and several TV's.
The breakfast was pretty solid... my friend and I liked it. There was a good selection and it was clean and well stocked.
Parking is underground at $23 a day. Not to bad considering the area. You can walk (5 -8min) to the Pentagon City mall and numerous other stores. There is a metro stop in the mall.
I would stay here again.... nice clean place with a good location and nice staff.
