The apartment is super convenient to pretty much everything. We love to walk (a lot) and did the capitol, white house, mall, and monuments with a full day of walking to and from the apartment. Since we were on a road trip, we needed a place to stash the car and this was absolutely perfect.
Claire was a wonderful host and let me bring our family dog last minute! The yard is mostly fenced in which he enjoyed.
We had three adults, and you should be aware that the bathroom is in the main bedroom. So if someone has to go in the night, they must go through the bedroom. This was no problem for us, but just thinking logistics for other people's groups. Even though the apartment is basement level, it has natural lighting with all the windows above ground to let in the sunshine.
We had a lovely stay and wouldn't hesitate to stay again!
