Apartment is very well stocked and has guidebooks, provided coffee and tea and a Netflix account connected to the TV. Blow-up mattress and the main bed were both exceedingly comfortable.
Where the listing says the apartment is an 8 minute drive to the city centre is inaccurate. It takes around 25 minutes to drive to the National Mall, and about 45 minutes to travel in on the subway, as the nearest subway station is around a 10 minute walk away. The apartment is in a quiet residential neighbourhood, though we were reluctant to walk back from the subway station on an evening as the area becomes quite dark, so we relied on ubers.
Overall the apartment itself was great, just a little further out of the city than we thought it was before we booked. If you are prepared to spend 45+ minutes on the subway to get to the tourist attractions, the house is perfect!
