I can 100% recommend staying in Oriella and Andrea's room - great value in Milan.
Oriella and Andrea are great hosts, super friendly, super responsive, and make sure everything goes very smoothly. I could check in very late as I had a late flight into the city, thanks for that!
The room has en ensuite bathroom and the suite is separated from the rest of the flat by a separate door. So full privacy, in addition Oriella and Andrea are very discreet.
Room and bathroom are impeccably clean and the room looks exactly as on the pictures.
Unfortunately, I haven't much explored the neighborhood, but it felt safe and connections by metro and tram were very convenient and fast to get around.
