My period at Alberto´s house has been entirely positive.
I stayed at his apartment for 9 nights, and he was always available to solve any issue I had.
It was a bit difficult for me to find the place when I first arrive, but I called him and immediately came to look for me.
The apartment is really nice, you can really feel at home. It is a bit far away from the city center (25 mins in bus) but it also well connected by public transport (bus & metro).
The bed was really comfortable and the private bathroom was tidy and clean.
You can also enjoy the yard at his place, on sunny days is very pleasant.
I highly recommend Alberto's place for anyone visiting Milan.
