We have just completed a long stay in Raffaello's apartment and it was great. The apartment is located on the first floor, serviced by a lift, up a few stairs in the entrance foyer.
The space is large and very comfortable for a long or short stay and is perfectly located, with two supermarkets, bars, restaurants and cafes all just outside the door.
Raffaello lives in the adjacent apartment and is available to help if needed.
If you have mobility issues be aware that the shower is over a hip bath and if not used to using this setup, takes a bit of flexibility to get in and out. That said, this is typical of most older apartments in Italy.
Raffaello is a great host and the apartment fantastic; I would not hesitate recommending this property to anyone wanting to spend time in the very beautiful Bologna.
