This is a great, unique house in Washington, DC. The location was perfect, about a 10 minute stroll to the Capitol and start of the National Mall, and right by the subway station. There are two great cafes just around each corner. The room was spacious and clean. The communication from the host family was timely and helpful. They even went out of their way to make sure we had a close parking space on the street with a free permit. Our family of four had the top floor, which also has a nice rooftop terrace, great for breakfast.
The main thing to be aware of is that it's a shared house, with three private rooms, each with private bathrooms, but shared kitchen and hall space. We had the unfortunate luck to have some loud middle-of-the-night guests below us. Nothing against the house itself or the wonderful hosts, it's just a risk in a shared space like this.
Otherwise great stay, and would recommend this place to anyone looking for a conveniently located house that's walkable to the central sights and many restaurants.
