Club Quarters is in a good location, close to the White House (although you need to walk a fair way to get around the other side if you want the classic White House photo).
I stayed in Room 311. It has a queen bed, large desk, coffee maker, TV (although it was a bit snowy), and plenty of power sockets. The bathroom has a shower (no bath) and a hairdyer. There is no in-room safe, fridge or minibar. The furnishings are not ultra-modern, but they’re OK.
The staff were very helpful.
The metro (subway) entrance is right next door, although it is not open on weekends, so I had to walk a couple of blocks to another entrance. The metro connects to DCA airport, which is very convenient.
