I spent 2 weeks in Bologna at Maurizio's apartment and could not have been happier. The apartment is nicely furnished and clean and the courtyard is a great spot to relax in the morning, afternoon or evening.
The bed is huge and comfortable and the kitchen facilities are good (though simple so you will need to visit the €1 shop if you want to cook anything special). Maurizio provides everything you need for your stay - including soaps, shampoo and washing detergent for your clothes if you want to use the washing machine.
The location is excellent, only a 5-10 minute walk into the centre of Bologna but away from the busy, noisey parts of town. There are a number of small mini-marts within 5 minutes walk, an excellent bakery one road over and one of the best restaurants in Bologna literally 2 doors down.
Maurizio himself is very friendly and helpful - even dropped by on my second night with some wine and gave me a lot of advise of where to go, see and eat in Bologna.
The only one minor criticism I have is that the wifi was not working when I visited, however Maurizio was working with the provider to get it fixed and even offered to loan me a laptop to use during the visit.
Without doubt I would stay in this apartment again if I am ever lucky enough to return to Bologna.
