My room had a single bed and small desk. It was basic but comfortable. It was very hot in Bologna when I was there but it was OK with the small desk fan in the room. The shared bathroom is clean and a good size.
Diego gave me good directions and messaged me to check I was OK when I was later than expected. He greeted me with a nice cold bottle of water and offered to make me a coffee. He showed me places to see and options for dinner on a map.
The apartment didn't feel particularly homely as Diego keeps some of the rooms locked and guests only have access to bedroom, bathroom and dining room. Having said that I understand why he would want that security and appreciated being able to lock my room.
The location is within 10 minutes walk of main bus and train stations and about 15 minutes into the city centre.
In short, Diego is a good host and this is good value comfortable accommodation in a convenient location.
