We enjoyed our stay in Chris’s apartment. It is very central, with a lot bars and restaurants nearby and accessible from the historic center by tram and metro.
As for the appartement itself, it is small but quite functional, we were very happy to have the AC as it gets quite hot in Milan.
The only con is that the window in the bedroom overlooks the entrance of neighbors so you can hear them come in and out at night.
Overall we recommend this appartement if you are on a budget!
