The 1BD was as described, and Daniel, as well as his family, was very nice. The flat is in a basement, but with a lot of natural light. It has the best AC I have experienced in my life, a 5 stars kitchen, a very confy bed. Maybe the only bad point (but not for me) is the bathroom (if someone need a lot of space for creams, etc... ).
The location is fantastic. You will be in the nicer place of Washington (I don't exagere). 10 minutes wald to the Metro. And 2 minutes to a supermarket (the ideal dimension).
Finally, just one suggestion: I am not fan of micro-waves, but probably it would be usefull.
Last point: there is a dishwasher!!!! I used two times and it works fine.
So, obviously, I would come back in another occasion.
