Checkin is perfect.
Hosts are friendly, flexible and truly helpful.
The place is a huge apartment with several rooms and two bathrooms, that are very clean.
I got a lock and a key from the host, so I could lock my precious things if I needed to.
A towel is NOT included.
Location is really good. It was my first time in Milan. I never used public transport in the two days, and still saw everything, sometimes even more than once haha. It is close to central station, to aperitivo-action, and to sightseeing places.
Get tips from hosts : they are good.
