We really like this place. The place is clean and the facilities are good. The information provided by the host is through. The host also provides several good restaurants in DC. The best part is the Washer and Dryer are inside the house. This is really convenient for us because we can wash our clothes anytime we want.
The location is good for most people, but maybe not very good for young kids. The closest subway station is about 15~20 min walk for kids under 10. If taking bus is fine, then several routes (90, 92, and others) are in front of the place. I am a Starbucks fan in Taiwan. The place is far away from any Starbucks (15~20 m walk), but the host provides very good coffee so Starbucks are not that important to me during out stay. If you want to cook by yourself, it might be a little difficult to get a grocery store. The closest one I think is Trader Joe's at the corner of Florida Ave and 4th St. I need to walk about 15 minutes to get there but taking bus is only 4~5 stops.
Overall, I think this is a great place. I will definitely stay this place again when I visit DC in the future.
