We had a nice time at Alex's place. The basement apartment was clean and very well-equipped (we were waiting desperatly for a kettle and a mocha machine :) ) communication with Alex was perfect, he helped us a lot getting around DC. The location was a bit far for us (as tourists) - 30 minutes with uber, 40 minutea by bus, and not too many cafes or shops around... But overall we had a nice time and enjoyed the place.
