My girlfriend and I very much enjoyed staying at Carlotta's apartment. The location is great (both rather quiet, but also within a short distance to the city centre, restaurants etc.), the bed (large convertible couch) comfortable and everything is clean and cozy. Though the blankets were quite thin, but there were more in the closet.
Carlotta is very friendly and even gave us some tips for restaurants and other cities to visit. There was coffee (for a moka pot) and some basic things for cooking. We can absolutely recommend to stay here, if you plan to visit Bologna for a few days.
