We had a very nice stay at Katias place. The apartment is big, very clean and has everything one could need, even for a long stay.
It is located in the far west of Bologna, directly at the train station for the local train and there are also busses - public transportation exists also at night, so its really easy to get down town and home.
We had some problems with the heating which were unforseable. Katia responded to my questions immediately, offered possible solutions and did what she could to solve the problem (on the new years day... thank you again for that!).
