We enjoyed our stay at Bernardo's apartment in Milan. We chose it for its close proximity to Central Station which was useful for a short trip.
The apartment was warm in winter (even without using the A/C) and the bed was very comfortable.
I was caught by surprise when I needed to download an app called Keesey to collect the house keys. Initially it felt like a nuisance but the Kessey facility was easy to use and provides charging, wifi and luggage storage facilities, which is very helpful.
