I have stayed in this Airbnb for a week and I recommend it 100%. The check in process was super easy and smooth, and the appartment is really impressive. Amazing decoration, plenty of space and all the appliances you need to make your stay in Bologna comfortable.
The apartment is within walking distance (and a very beautiful one with all the porticos, I must say) from all main tourist attractions and also close to the San Luca Sanctuary, which has an amazing view of the vicinities.
Also, Nicola is a very thoughtful host, checking to see if you need anything and providing accurate information whenever I asked for.
