S is a very attentive host. It was easy to get in contact with her. Upon arrival bottles of water where waiting and she also provided coffee. She also asked how we were doing during the stay.
The apartment is nice, located in a safe neighbourhood and more than big enough for 2 people. It is about 15 minutes walking to the nearest metro station, from there it is about 5 minutes to downtown DC. Walking to the mall takes about 40 minutes. A cab costs about 15 dollar, so excellent location.
