Mariarita is a great host!
I saw her only once on arrival (I stayed 6 nights) but she communicate and help you with the message all the time.
She even sent me a message one day before the arrival to communicate that I'm allowed to do the early check-in! That was very helpful after long flight arrived at 07:00 in the morning!
The room is small with single bed in the China town but very clean and you have your own bath room and the entrance to the apartment!
Easy access to the transportations, lots of restaurants/bars around and very close from the night life of Milan!
