We had a really nice time staying in Bologna, we were met on time by one of the hosts to pick up the keys and communication was very good throughout.
The apartment is on the third floor of a nice building on a residential street. The location is very convenient for walking to the centre of Bologna (takes about 10 minutes). There are also a couple of supermarkets close by. The flat was very clean and spacious too with nice furniture.
I would recommend staying here if you come to Bologna.
