Me and my friend had a long stay in Bologna due to a course (2 months). The place might be outside the walls, but it is an okay walk to the center, well served with buses and easy to bike. There are parks around with good ambience. And being outside the walls wasn’t an issue, it was better for us actually.
All the rooms have AC which is a blessing, kitchen has utensils and pots, and you also have a nice living room to spend time!
Cristina was always kind and available for questions and helped us with some troubles (friend had to go yo the hospital) and even dropped a baking tray for us.
And amazing place with amazing hosts. Super recommended.
