I stayed at Enricos place for two nights. He gave a very good description of how to get there and where to find keys etc. Enrico himself wasn't there while I stayed in London and I also didn't meet anyone else in the house which was fine as I came and left late.
The room was very tidy and the mattress is very good. The bathroom is tiny but has everything you need.
I liked that Baker Street is in walking distance.
I would definitely recommend the place.
