Overall: City living: problems getting both air and quiet: choose only one.
Check-in: The owner lives 2km away from the b&b: you must either have a phone to call just before arriving or be able to state exactly when you will arrive.
Language: Italian with a tiny amount of French and English. My Italian is very poor, but it was better than either his French or English.
Space/decor: the style of a good quality hotel: decent space in the rooms, modern bathrooms.
Comfort: The bed was reasonably comfortable and had the right amount of light coverings for the temperature. I assume more blankets will be supplied if the weather is cold.
Noise: Our room overlooked the main street, but there is little traffic at night. The giant problem was one of the town bells -- it clanged at 15 minute intervals all night. I have no idea how anyone could get to sleep with it: just as you are dropping off, it jerks you awake again. However, the windows are very good insulators: shut them, and there is no problem from the noise. From a ventilation standpoint though....
Heat/ac: No a/c, no ventilation controls in the room. If you close both window and door for noise, you'll have no air circulation. If you open the window, you'll need ear plugs for the damn town bell. If you open your door, you must trust that the other guests will be quiet and that no-one will walk in on you. Hmmmm.
Internet/TV: No internet. I don't think there was a TV either... maybe in the common room.
Breakfast: not provided for those only there one night
Parking: Behind the bank nearby.
Distance to attractions: right in the centre of the old town.
