If you're going to be in Washington DC for any amount of time, for any reason. And you happen to come across this listing, and my review. You need not look further. If it's available, BOOK IT!! Everything was perfect from the location to restaurants, bars, stores, sites and a metro station. All of which are a 5 minute walk.
The house itself is perfect for a lone Traveller such as myself or a group of friends. It has everything you'll need to enjoy a stay and feel comfortable.
As for the host... River. She is amazing! She will bend over backwards to fulfill your every need if you're not satisfied. She checks on you when you first check in and makes sure you get settled in. She offers help in/by any means. She knows it all. I could go on and on about the best Airbnb experience I have ever had this far (which is this one) but I won't.
If you don't book and stay here you'll be making a mistake and missing out on such a remarkable experience.
