I can only say staying at Chris' house was an amazing experience. Not only he is an awesome host, but a great, fun and caring person. The house is located at an enviable location, everything is walking distance (Bars, Restaurants, Movie Theater, Markets, Liquor Stores, Clubs, Chinatown) and if I needed go a bit far, Uber would be the solution and it is very cheap with or without splitting the fare.
The house is very comfortable, very high tech, and the room is very spacious with a huge TV. I stayed by myself in the room, but if you are a couple trust me you will have enough space. WI-FI is really strong and I never had a problem with it.
I made his house my house for (2) months and I have decided to stay another month because it is great. I am glad I made the decision to stay in his house and definitely I will be staying there if I ever come back to DC.
