We stayed at Maurizio's place for only a night. We arrived late as we did a day trip in Verona from Venice. I was a bit worried that Maurizo will get upset because we arrived at around 11 pm. But he was very welcoming, he even called on our way to check if everything was ok.
The room was clean and we were provided with all the essentials. The location of the flat was also not bad, as everything you need to see in Milan are just close by.
