It's a really great apartment in a perfect location. Lot's of light, lots of closet space, high ceilings, squeaky clean. Air conditioning, separate bedrooms and bathrooms.
We never saw Cristiana, but communication was good enough.
Few things make it great, but not fabulous:
a) there's no microwave in the otherwise fully equipped kitchen;
b) one of the bathrooms has a huge jacuzzi tub, but only a hand-held shower, quite impractical and that left us 4 people with a single shower in a claustrophobic cabin that could have been a foot longer-so we created a shower schedule in shower rush time
c) there are no mosquito nets on the big French door type windows, which makes getting fresh air not from the AC an issue-and we were surprised how big a problem mosquitos are in Milano, so be prepared with lots and lots of bug spray
