Me and my sister stayed for 4 days in London at Elisa's room. The room and the house is as she described it and you can see it on the pictures. The roommates are in fact really quiet, we only saw them like 3 times. But we have been in the city for the whole day and only came back there to sleep.
The contact with Elisa was really nice. We both were a little unexperienced because it was the first time using airbnb for both of us, but everything turned out nicely. I would stay there again.
