We chose Alessandro's place because he allowed late check in and luggage storage as well as being walking distance from the Duomo. It's also only one metro stop from Cadorna which made it easy to get from/to the airport by train. As Alessandro wasn't in town, his assistant who lives upstairs checked us in and out. We didn't spend much time in the room, but it was clean and serviceable, if a bit warm; we couldn't work out how to turn off the radiator and so just opened the windows (which luckily open onto a courtyard, not the road). We left the sofa bed out, so space was a bit tight, but otherwise, it was fairly comfortable and quiet. There are restaurants and shops right outside, including a mozzarella bar (which we tried) and a gelato shop (which we didn't, but wish we had). As a bonus, we were allowed to keep the room until night time as there were no bookings after us.
