Carmine was great. I messed up our arrival time, and he was very understanding and friendly despite the time he lost. The apartment has 4 bedrooms, a bathroom, and a kitchen. We rented one nice room and we slept well. The street outside is a little loud, but there was a fan in the room which helped drown out the outside noise. I appreciated the washing machine and the wifi. The location was absolutely perfect: close to the train station, not far from museums and churches, but also a slightly cheaper area to grab dinner or get gelato.
