I had a great stay at Andrea's place. I didn't get to meet him but he was very responsive to my messages and questions, and even came in to fix something during the day when I was out and about.
The apartment is small but luminous and was exactly what I needed for a few days in Milan. I liked the neighborhood (and there's excellent pizza just around the corner!) and it was very easy to get to from the airport/train station. Would recommend it!
