We originally planned only a week in DC, but kept extending it as Kathleen's place and hospitality was so fantastic. The room is spacious with everything you might need -- every room has a coffee maker, a minifridge, plenty of towels, AC, etc.
There's no kitchen for cooking, but with all the restaurants within a 2 minute walking distance you won't want to cook anyway. The Logan Circle area is vibrant and happening, and Kathleen's house is right in the middle of the action.
It was our first time staying in a shared airbnb (rather than booking a full house), and it was a great experience. Other guests were kind, quiet, and respectful, and the shared bathroom was always available and kept tidy.
Highly recommend!!
