We really enjoyed our stay in Washington DC. We spent 3 nights (we should have stayed a few days longer, because there's so much to visit in the city !)
We didn't meet Chiazo but we had all the information we needed for a smooth check in (and check out). The apartment was clean and comfortable, large enough for a family of five.
The apartment is located in a transitional neighborhood. It is a 7 minute walk from Columbia Heights metro station, which takes you downtown very rapidly.
