This apartment is very good for what we needed, 10 min walk to grocery store and metro in DC to see the sights. As described from other travelers the ceiling is thin and you can hear footsteps. Sleeping on the couch is not for light sleepers, the refrigerator does make noise also at night.
Bring your sleepers as the floor can be cold.
Otherwise as described, great for a family, has two separate bedrooms with comfortable bed in each.
