The apartment is ok for 2 people, for 3 it would be too small.
Location is great, very close to Duomo, food and public transports.
Cleaning could be better, specially in the kitchen. There were leftovers in the fridge from previous hosts. The bathroom was also a bit messy.
Check in was a bit late, as there was nobody when we rang the bell. When we got to the apartment, it was not clean yet.
Not very flexible during check out as well, not even to leave the luggage after 1 pm.
I see some very good comments about Marco, bit we did not meet him at all.
