This place was amazing and way better than our expectations.
Gianluca's wife was outside waiting for us when we arrived, she showed us around and texting communication was instantaneous (even though she doesn't speak perfect English, we managed our way with google translate)
The place was clean, and well-equipped, with air conditioning, a washing machine, a good internet connection, and a coffee machine. And two key examples were provided so it allowed us to split into two groups and hang out separately. The location is also quite central (near the central station) metro was at 7 min walk and it takes you to the duomo in 15 min or slightly less.
I highly recommend this place to anyone visiting Milan for work or for vacation.
