I definitely recommend staying away from this apartment and this host.
We arrived less than half an hour late to the checkin because our bus had a delay at the border. I wrote the host three hours before arriving, that we might be a bit late and they said they will not check us in and we had to wait until the next morning. I made the offer to drive anywhere in Milano to pick up the keys or meet them whereever they wanted but they simply ignored this message. Fortunately, we found a hotel for the night, otherwise we would have had to stay outside.
In the apartment, the water did not flow out from the sink and thus we could not use it properly and it started smelling. The shower did also not work properly and on top the airconditioning started leaking, which led to our luggage getting wet and damaged overnight. We asked for a refund for those inconveniences but it was refused.
I have used Airbnb for over 5 years in more than 10 different countries and never experienced such a bad treatment and apartment.
