The hosts are great, with Mattia and Sandra both being very responsive and accommodating.
The apartment is quite large and would be great for a longer stay with a full kitchen and a washer/dryer, plus lots of wardrobe/storage space. It would be suitable for a family too.
It's in a great location, just a short walk from Piazza Maggiore and the main sights of Bologna, but away from the bigger crowds. There are some really nice cafés, restaurants, and bars in the neighbourhood too.
