I only had 2.5 days in Milan and this place was ideal.
Location - 5 stars. All the major inner city sights of Milan (Duomo etc) were very close, and accessible by foot. Even though I had a car I didn't use it. Lots of great shopping right outside your door....the main Duomo Plaza 5 minutes away on foot.
Apartment - 5 stars. Clever use of space, even though it was small it had everything you could need, even cookware if you wanted to make something in the mini-kitchen. I always love having outdoor space and the patio was perfect. The window in the bedroom opened so with the patio door open, you could get a nice cross breeze. No real view from the patio but you could also sit out there with no one looking at you. Bed/pillows comfy - typical European firmness. High security building. Never felt unsafe.
Noise/cleanliness - 4 stars. Some ambient street noise and construction early in the morning. The unit was clean - bedding, couch and towels smelled a little like cigarette smoke, although the unit is non smoking. Also, some cobwebs and spiders in the bedroom roof. Had to clear them out before I went to bed! Given how clean the apartment was in general, surprised the cleaners didn't notice them.
Parking - 5 stars. Although the listing didn't mention parking, the apartment building does have parking for 20 euros/day. Convenient. *Note: I arrived on a Sunday and you can drive into the center of Milan without any issues on Sundays re: fees etc. Other days are not so easy.
Would stay here again and recommend it!
