The house is lovely and in a gorgeous area. It is very quiet, but close to a number of busy streets with lots of great places to eat, drink and shop. We couldn't get over how nice Georgetown is as an area. As for D.C., there is a bus stop 5 minutes walk from the house that puts you on a $1 circular that takes you straight into the tourist hot-spots. It's also easy to grab a cab or even walk if you fancy stretching your legs.
For the house itself, it feels surprisingly spacious, is clean, and has been nicely decorated and set-up. The living room area is particularly nice. The shower could be better, and the mattresses were a bit firm, but these really are minor points from an otherwise fabulous property. All of us would stay here again without even considering alternatives in the D.C. area. Fausto was easy to communicate with beforehand, and there were no issues with accessing or leaving the property.
We'd also recommend a couple of local bakeries: Bean Counter and Patisserie Poupon - Georgetown.
