Fairly easy to find, doorman had to help us buzz up to his apartment, but I'm confident marco would have answered promptly had I needed to call. After showing us around the apartment and clearly explaining the cleaning situation, marco gave very helpful suggestions about things to do / places to eat around the city. There was a decent amount of street noise, but it seemed to quiet down around midnight and stayed that way until 8am (and that may just be how Milan is on a Thursday night!). Despite arriving in the morning and leaving late the following evening, marco allowed us to keep our bags in the apartment for the entirety of our stay, which was incredibly gracious and helpful.
