My girlfriend and I spend a few days in Milano and really enjoyed our stay at Katia's apartment. It's on the smaller side, but very cosy and full of cute little details. She thought of everything and put little notes and hints everywhere. The place was very clean and everything one would need was there.
The tram line number 1 stops right on front of the house and from there it's roughly 20 minutes to the Scala. This was super convenient and we used the tram everyday. We would definitely recommend staying at Katias place :)
