The host family is very friendly and helpful. One of the sons (also great English speaking gentleman) offered my 5-yr old son some toys to play, and my son loves hi-five with him. The apartment is very large and the beds are comfortable. It is 15-18min to the airport, by taxi is around 16-18 euro, by airport bus is 6 euro per person, which you can get off half way or to the central station then catch another city bus. Because the apartment is between the airport and the city center, so it's easier especially if you travel in groups by taxi from the airport. There are coffee shops and delicious restaurants nearby, very friendly neighbourhood. When the weather is sunny, we prefer to walk to the city center, it's around 25 min slow walk. The bus is convenient when you download the local transport app Roger to buy the tickets. We enjoyed our stay in Bologna, it's friendly, not so crowded with international tourists, food are good, walking around is easy. The apartment is fully equipped, but we spent so much time in town, that we didn't have the need to use the kitchen at all.

only some minor thing: It would be convenient if there are more towel hangers in the bathroom

Great location, knowledgeable helpful hosts and really comfortable beds.
