A neat apartments which fulfils all your basic needs for a trip to Milan. The bed, bathroom and kitchen are fine. The location is okay, around 25 minutes walk to the centre/Duomo (we used one of the bike rental apps to cycle to the centre), and the street in which the apartment is located is nice. There is a supermarket and it is located in Chinatown, so lots of little Asian restaurants.
However, the walls of the apartment are very thin. We had been warned to not make too much noise, and to be quiet at night, which we tried to do. We were able to hear our neighbours talk and walk, and when they were asleep, we could even hear them snore through the walls.
Also, despite of all the warning signs in the apartment and the building to not smoke, the apartment smelled like smoke very badly. We think there had been a party before we arrived, so that might have caused it to stink, but it was extremely unpleasant and the smell was in everything (bed, curtains, and eventually our clothes), so it might have been a one time thing.
The communication with the host was excellent, multiple times before our stay and clear explanations of the check-in process. When something did not work while checking in, I sent a message and within 2 minutes it was fixed.
