Stayed here for four days and would have to say overall very nice. It's within 5 minutes of the Rosslyn train station, very walkable with alot of food and shopping nearby and easy to access everything (also ten minutes away from DCA). Do note it is on a hill so getting to the hotel can be a bit tiring after spending the whole day out.
Hotel was overall very clean with only a few minor issues: our shower had not cold water (no matter which way you turn the water it was either lukewarm or hot), bedroom AC didn't really work (it was a suite so the main room AC worked thank god), and there was a bit of a weird smell in the room though it was somewhat faint. Bathroom was kind of small and did not have a fan, and the showerhead was not nailed down to the wall so it moved if you touched it.
Service was good, and this was one of the few places that offered a very late check out (2 PM) which was nice. It gave us the ability to travel the city a bit longer before hopping onto our flight which was at 4 PM.
Overall a solid B+/A- hotel and would not mind staying here again.
