Althoght check-in was from 3pm, the room hadn’t been cleaned at 6pm yet. But the Host anwered quickly for my message, and the cleaning lady arrived soon and cleaned the room properly. Therefore I recommend to ask that the room is ready, if you have a busy plan.
The location of the apartment is not marked correctly! The actual address is Calle del Sottoportico Scuro 1003.
Otherwise the apartment is beautiful as in the pictures and in a good location.
