Charles and his roommates were incredibly nice and welcoming. They gave us tips what we could do during our stay in London and also drew us a little map in order to get around :D
Although we just stayed for a few hours, our stay was very comfortable and the bed was really nice. Additionally the house is located very close to the Overground, which made it easy to get around.
To anyone staying in London and looking for a place to stay, I definitely recommend this room.
