We spent less than 12 hours in Milan. The apartment is just what we needed - close to the central station. It is very small, but we didnt need more than that. There was a cigarette bud on the floor, and it was a bit dusty. Otherwise, it was ok and seemed clean. The water pressure in the shower is very low too.
Having said that, the place is sorounded by restaurants and is 2 minutes from the central station, so it is very convenient. Paolo was very communicative and his mother Maria was very nice.
