I would say Francesco is one of the reason that made us love Berlin.
He is a very warm host and provided a booklet of information which are all useful for tourist made by himself.
The place its self is warm and cozy in winter and the location is great, near to the underground/tram station and with loads of supermarket/restaurant nearby.
Good wifi and well equipted house.
I would definitely recommand him as a host.

One short story is, there was an unexpected construction work downstairs which created abit of noise in the morning. Even it was not Francesco's fault, he aplogized for it and gave us a bottle of wine as a compensation. That's very sweet of him.
