I booked Stefania's place for three weeks for my mother. We live in the area so it was close to our place, otherwise Citta Studi is not a great location for tourists to Milan. The place it good because it's ground floor, bright and has the outdoor space which the back part of the apartment looks over - it is the highlight of the place. The bedroom is at ground floor and faces the street, so there is a feeling of not much privacy or security from the street (the street is not particularly nice).
A significant problem with the place was that is smelt very strongly of cigarette smoke. Clearly someone had been smoking a lot IN the apartment even though the listing clearly stated "NON-SMOKING HOUSE". When I raised this with Stefania she said that it was bearable and offered no solution or compensation at all. It was completely overpowering and unbearable. My mother spent the last week of her stay at a hotel.
