Welcoming and explanation about the place and Milan city from the host are perfect.
The location also perfect, very close to duomo. Size of the apartment also good.
The problem only with the bathroom is flooding, the water - there is white colour in there and no AC remote (if in that time weather not hot that would be ok, but in that time the weather was very hot).
The elevator is off after 10pm or 11pm. And start operation again at 9am or 10am.
