Shaun's place is very clean and welcoming. Shaun is a nice guy, who can help you how to get around in Washington D.C.
The room is spacious for two people and we felt comfortable. If you have no car and want to visit downtown by public transport, it will take some time. It is a 15-20 minute walk to get to the free tram, which takes you to union station in about 20 minutes.
The room has central air condition, so there is no possibility to modify it. But that was not a problem for us. We enjoyed our stay and recommend the room if you want comfort for a good price a bit outside of D.C.
