I was in DC for a week and had the pleasure of staying with Tom and Adam. While I did not meet them in person, they were very communicative, replying to my emails very rapidly, and ensuring that I was well taken care of and comfortable during my stay. Excellent hosts!
The apartment, accessed through a picturesque garden with banana trees and small statuettes, is very comfortable and spacious (two rooms) with a large bathroom. It is well air conditioned (which was wonderful given that it was ~95C everyday when I was there).
The apartment is walking distance from many restaurants, bars and cafes, and is located in a beautiful neighborhood which comes across as simultaneously quaint and modern. It is a short walk (~5 mins) to the green line which allows an easy commute around DC.
I highly recommend staying here!
