This flat is really comfortable, cosy, clean and it is well connected to the city center. There is everything one might need for a stay of a couple of days to months: pans and pots, dishes and cutlery, a dishwasher and a washing machine. It is also well served by public transport.
Andrea was a very friendly host. He replied in no time to my request, and as I arrived, I found him at the bus stop, waiting to pick me up.
One suggestion to anyone who would want to rent his flat: ask him about eating out in Bologna, he really knows his stuff!
I'll certainly reconsider renting the flat again, should I be in Bologna any time again.
