Alberto and Valentina were very welcoming :) we received all the necessary information before arriving, the flat is easy to find and easily reachable with public transport. The bus stop is very close from the flat, and there are buses until late in the night even in the week, which is very convenient.
The room was clean and comfortable (same thing for the private bathroom), with a view on the garden, in which you can have breakfast in the morning :)
We did not have much time to chat with our hosts since we stayed only 2 nights, but we enjoyed the time we spent there, and I would recommend this address for a stay in Milan. Alberto and Valentina, thanks for your hospitality :)
