Catherine's place is in a great location. In the middle of a neighborhood with a lot of bars and restaurants, and easily walkable to the metro. It's set off the main streets on a little walk street so the outside noise isn't as bad as it could be in the area, but if you're a light sleeper, you may want ear plugs.
The space itself is very unique and nice. Catherine is quick to respond, and checking in and out was very easy.
Watch your head coming down the stairs to the common areas if you're taller :)
