I'll start with the good:
the appartment is in a very good location to be in milan (porta Venezia)
it's close to everything you need or the metro/tram stations
we were allowed to get inside before the check in time when i asked on the day of arrival too early
as for the bad:
we didn't had a blanket cover (duvet) on the first night and we had to sleep with a towel which was very inconvenient, the cleaning lady forgot to bring it back after cleaning
the communication for solving it wasnt as good as i would've hoped, i was told she'll bring it back, but not when, and after she brought it when i wasn't at the place i wasn't informed so i thought i didn't get it and just got mad for nothing which is a shame
