Before my stay Alex was capable to reply very quick to any questions I got.
The keypad at the front door allows a very flexible handling with entering/leaving his house. It works quiet fine for me. The room was exactly as described. Cleaned and tidied up. The bathroom, imho, was clean, even if there were 3 people using it. I could do my laundry using his washing machine and dryer. Finally I had the great opportunity to go out and a have some beers with Alex. This was some kind of a highlight during my stay in Washington.
