We had a very nice week in Heather's basement room. The room has comfortable space for two persons, with comfortable beds. There are no windows, but this makes the room dark and quiet, which is great of you are recovering from jet lag.
The room has a private bathroom with a great shower. It is a short walk away from the bedroom, near a communal area (some people might prefer to bring a bath robe or dressing gown).
The kitchen (fully equipped), living room and pool are shared with the host and any other guests. Heather's two pets (a dog and a cat, both friendly) roam freely in these areas.
The house is located about 10 minutes walk from the Eastern Market metro station. The area had plenty of restaurants and several food stores (we preferred Trader Joe's, near the metro) if you plan to self cater. The market hall should also be visited, it is particularly nice in the weekend.
This has been one of our best Airbnb stays so far. We would be very happy to come back.
