The apartment itself is on a great location, super lively neighbourhood. The place is definitely suitable for a longer stay as well, because of the well equipped (tiny) kitchen & laundry room.
The downside of the space is that it's hard to warm up, since there is not really a heating system.
Also a big disadvantage was that we had to pick up the key in the center of the city, which is not at all close to the apartment. This resulted in a journey of 2 hours through busy Milano traffic before we finally arrived in the apartment. Assuming this was an exception, but good to keep in mind when you discuss your arrival.
