I stayed in Rosario's House for a month. I felt always welcomed in their house. The bathroom and kitchen are shared with this family, but there was not any problems during the times I wanted to cook. They really care about their own personal space but they are very respectful of your own privacy and needs as well.
Cleanliness was spot on and they expect the same to you which was never a problem.
The room is great, very well furnished. Great amenities. There is everything you need.
Distance to station is great too, literally 3minutes walking to Stockwell station which is
well connected to any destination in London.
I would recommend to any travelers!
