This place is really cozy and stylish. We communicated with Eva, who's co-hosting with Ivana, and she replied very quickly to all our questions. We didn't get a chance to meet them, the check-in was made by one of their collaborators (really nice guy).
The apartment looks exactly like in the pictures. It not to big, but ok for two persons. It is very well equipped and very clean. Also, the bed is comfy.
It is located 2 mins walk from a subway and a bus station (4 stops from Duomo and 8 stops from Milano Centrale Station - 15-20 min)
Cons: The bathroom had no window or a working air ventilation.
I really recommend this place for visiting Milan!
