Wonderful, unique little apartment that comfortably has two bedrooms. Can't do better for location and price.
You definitely should be prepared for going up the few flights of stairs as it is uniquely positioned in the upper level of an old time courtyard, but that didn't bother us. Definitely would think about it if DC was experiencing a snowstorm or something.
Super communicative hosts and we appreciated their help.
Note that the crib is still just a pack and play (not a full crib) if that's what you're looking for. Washer wasn't operational when we stayed but that's not a big deal, it recently broke and nothing the hosts could have done better!
