First, the host is no less than amazing. We asked to check in early and she worked very hard to allow for this. She was very communicative, answered each and every question I had, and responded very quickly. I really can't ask for more.
The apartment has all that a family needs, and more. It has several flat screen TVs, Micro wave over, regular oven, washing machine and dryer, and dishwasher. you get all the stuff you need to enjoy these, such as washing powder etc. This makes your stay very comfortable.
the apartment is very close to a metro station that takes you directly to the national mall.
To sum it up: great apartment, and great host.
