This apartment was clean and suitable for a one-night stay in Milan, but in general we faced several problems.
We are a family of 5 and stayed there for one night. The apartment had three bedrooms, two bathrooms and a small kitchen - no living room or dining room, no place to chill in the apartment. Even though there was an elevator, to reach the elevator we had to take several steps with our heavy luggage.
When we arrived (to be fair, we were 15-20 mins late due to train delay), there was no one to check us in and the doorman wouldn't let us enter the apartment. We had to find a hostmate staff members' number and ask the doorman to call them to be able to get the permission to enter. Some two hours later, when we were already in the apartment, relaxing, a hostmate staff member entered the apartment out of the blue! No knocking, no ringing the bell. Finally, contrary to what was mentioned on the Airbnb page of the apartment (the main reason we booked it), we were not allowed to leave our luggage in the apartment or anywhere in the building for that matter, so we had to carry 6 luggages with us and pay for storage space in the central station.
The house itself - other than being small for a family of 5-6 members - had no problems. It's the way that communication, check in and check out were handled, that created an unpleasant experience for us.
