This is a nice apartment in a very strategic location in Bologna. You're 5-10 minutes from the train station, from Piazza Maggiore, from great restaurants, from public transport.
The kitchen is good sized and exceptionally well-equipped for an AirBnB; if you want to go to Bologna to practice cooking, this would be a good choice. The living room/dining room (air conditioned) is also a good size, with windows delivering lots of light. There are three bedrooms (2 of which are air conditioned), 2 doubles and a very small single. Beds are pretty comfortable with standard Ikea-level mattresses.
There are two bathrooms; one has a shower.
Everything seemed to work pretty well, although the apartment hasn't been recently renovated, it was a pleasant place to stay.
The landing for this apartment has several others (3 I think) and you share together a nice terrace in the center of the building. The heat wave had decimated the plants and made it too hot for us, but presumably during cooler months it would be a pleasant place to stay. At least one of the other apartments at that level is an AirBnB run by the same host, so if you are two families together, you could talk to her about renting both at the same time. A nice plus.
During hot summer months, only two of the bedrooms are really useful, so this would work for 1-2 couples. In more moderate seasons, the third bedroom would work well for a child or single who doesn't mind a small room. Because there's a second toilet/sink, sharing the single bathroom shower shouldn't be a problem.
This would be a good apartment for someone looking to explore Bologna, especially arriving by train. The host is very accommodating and was extremely helpful in giving us restaurant recommendations and current events. She was very communicative and wanted our stay to be a good one.
