Below I have listed the positive and not-so-positive things about the apartment(staying).
+ Great Location, close to the centre Duomo, close to supermarkets.
+ The check-in and check-out is easy, due to the locker instructions.
+/- The air conditioner worked but only in the bedroom, the living room was very warm and also the remote of the air conditioner didn't work so cannot change the speed or temp.
+/- The apartment seemed cleaned but it's old. In the pictures it looked more modern.
+/- The host was fast to reply (most of the times) but unfortunately not so helpfull! I required an earlier check-in because a 3pm check-in is very late, above all I was with my family and they were tired, but the host requiered an extra payment and to be honest I didn't find her that helpful!
