Marco's place is amazing, his book and movie collection make you want to stay in :) We were visiting Milan for a few days and he left us everything we could need for breakfasts, which was greatly appreciated. We also got our groceries right downstairs and were able to cook for ourselves without issue as his kitchen is very well set up with all the things you could need! Marco was easy to reach and readily available when we wanted to extend our stay for an extra night.
As far as location goes, it was perfect! We went everywhere we wanted to go by foot, but if you want to take public transport, the tram is right in front of the place and the metro is only a short walk away.
If we are ever in Milan again we would definitely contact Marco! Highly recommended!
