Francesco is very nice a happy to accommodate the needs of travelers. He provided me with maps of Berlin and helpful tips for where to eat, etc.
The studio is very clean and well equipped - all dishes in the kitchinette, blanket, toiletries...I found everything I needed in my 5 days of stay. The area is quiet and studio's windows facing inner courtyard, so my sleeping was completely undisturbed.
Francesco lives right next doors, so it is easy to ask if you need anything.
