I really enjoyed my stay at this apartment. It's in a fantastic location in Adams Morgan, surrounded by restaurants, bars with live music, independent book stores, coffee shops.
As mentioned in other reviews though - that means there's usually quite a lot of noise, either from music from the restaurants downstairs or people outside. I was staying Sun-Wed in winter so it was probably quieter than at other times, and I knew what I'd signed up for so it didn't bother me, but guests should be aware of this when booking.
The apartment has a big open lounge kitchen, lots of natural light and windows onto the street, well equipped kitchen, fairly small but comfortable bedroom, a nice bathroom, fast wifi, big table to work from, washing machine etc. Very responsive host. I would definitely stay again!
