We had a great time in Milan while staying at Marco's place, the house was clean and Marco provided everything we needed. The check-in and the check-out took place easily and we had no issues whatsoever. Marco's place is very close to the metro, namely M3 (metropolitana nr. 3) which will take you directly to the Milan Cathedral ( duomo) in approximately 15 minutes. From there you can also easily find M2 and go visit other nice places in Milano, such as Castello Sforzesco. There's also a Mc'Donalds right across the street and you can also find a supermarket and other nice places very close to his home.
Overall we had a great experience, Marco was a great host and I recommend staying at his place!
