Constantin is super fast at responding and when we arrived late, he was very flexible! The room is big and there are two desks, so each person can sit down with a laptop. Right next to the house there are some local pubs, takeout places, and grocery stores. Central London is not far away and we would just walk to the underground and used that. Constantin was not not there for most of the trip, but we chatted with a very nice housemate of his. The space was generally clean, but we had a few minor issues that can easily be overlooked. We would very much recommend Constantin!
