We had a wonderful time in Eva and Marshall's AirBnB in Washington.
The apartment was new, modern and elegantly furnished, nice and clean. There was even a garden, so you can sit outside when the weather is nice. It was in a quiet street with lovely houses in an interesting neighborhood. There are some good restaurants, pubs and shops (the Thai one is very good). We didn't cook (lack of time), although the kitchen is very well equipped. The apartment is also conveniently situated, within walking distance of the metro station and bus.
Eva and Marshall came to welcome us and showed us everything. The last day they were very helpful: we could leave our suitcases.
Whenever we get the opportunity to go back to Washington we would like to stay there again.
