We had a very nice time in Christian's flat. The place is no different from the pictures and can accomodate 3 or 4 people without any problems. It is in walking distance to Piazza Garibaldi where the main train station is located. The only down side is the low ceiling in some parts of the flat which I even managed to bump into one morning. I guess being a tall guy serves you no good here...
On the other hand, Christian was a very friendly and helpful host. He welcomed us with some nice pastry and gave us info about all the things we wanted to know.
