Sam and his partner were very nice and welcoming.
It was a last minute trip and a pretty short one (just one night and the day after) that I had no time to prepare. Sam saved me a lot of time by pinning in Google map, on my phone, several places to visit. They were great recommendations and I enjoyed them. He knows the city very well.
The place is better located than what I thought when I looked at the city center on the map (it was my first time in Milan). It's walking distance to the Duomo (the big iconic cathedral), you'll need public transportation to reach the place from the central train station though.
