My family and I loved staying here! The place is beautiful - hardwood floors throughout and a very nice patio area. The neighborhood is wonderful as well. Capitol Hill was a short walk. Union Station is also a short walk. An area with two blocks of food places (including breakfast places and a Starbucks) is also a short walk away. The Smithsonian museums are technically walkable as well, but it is a bit much if its not and/or you have younger children. Take a taxi or uber/lyft instead.
The folks who manage the place are also wonderful. We had a small issue with the washer being broken, and they did everything in their power to remedy the situation.
We would definitely stay here again!
