Marcello is friendly and courteous - his apartment is awesome: clean, room enough for two people, has some italian breakfast items, the best linens EVER and a sizable shower with good water pressure. :-) And it's close to everything - walking distance. Just lovely.
While the neighborhood is quiet and the apt. is on the ground level, there are two things you should know: the apartment is not bright, meaning not a lot of natural sunlight. But it isn't dark...just not very sunny. Secondly, when you open the window in the living room, you can hear folks having conversations outside.
That being said: highly recommend the place. Suitable for a nice stay in Bologna. Close to everything - and a great cafe is just across the street from it.
