We mainly communicated with Paolo of the Samuel and Paolo duo, and we had a fantastic experience. The location is literally one parallel street away from the Duomo, and even so, the apartment itself is quiet and we had the best nights sleep of our stay here. Paolo was prompt in responding to communication, and was waiting for us right at the precise when we agreed to drop off our luggage (as travelers without working cell phones in Italy, having a reliable host was very important and super helpful). We stayed at a number of AirBnBs throughout Italy during our two week trip, and this was easily one of the best ones, and we are grateful for Paolo's both friendliness and professionality. We would definitely stay here again.
