Monica: is a great host, she is always on top of every need.
The place: is spacious and super comfortable. It has all the amenities. I believe everyone needs to take into consideration that it is underground and there is not much natural light all day.
Location: It is is not a 'nice' neighborhood to be in and walk around, it has a mixed crowd. Not bad, but not for everyone. Specially if you are looking for the glamour of Milan, it certainly does not have the feelling to it. Not far from the center of the city by metro. Around 20minutes to Duomo and 25min to Parco Sempione from the house.
I would recommend this place.
