Me and my husband stayed at Carlo's flat. We didn't meet Carlo in person. But he is easy to connect via airbnb and he replied us rapidly. Carlo and the caretaker who welcomed us (so sorry that I forget the uncle's name) are both very nice.
Room condition: a perfect room for two persons. Nice and clean room just like shown in the photos. The room is well equipped with everything needed. Very very convenient!!! Wifi, Shower, washing machine, kitchen...all in good condition.
Location: several cafe bars where can also buy traffic tickets in a few steps. A Japanese restaurant where also can packed Chinese food, a Turkish pizza shop, a few steps walk, both nice and cheap. A very large supermarket in 15 minutes walk, but just 2-3 stops by bus 47 or 74. Traffic to city centre and train station is very easy with bus 47 and 74 connected to metro or tram. The neighborhood is very quiet and there were little people on the street. We don't know the safety condition, everyday back before 8:00pm and nothing happened. Maybe we were just thinking too much.
We easily arrived Carlo's flat from airport with his instruction. When we arrived the flat, Carlo was just asking where we were through airbnb. And the caretaker came down and helped us open the gate right away.
