We did not meet Sabrina but the key handling over worked perfectly. The nighborhood towards the naviglio pavese is great, at night just avoid the streets on the opposite side, the one towards the naviglio grande. Oherwise the location is really good for milano and with the tram you'll be in duomo in about 15 min.
Shampoo and soap were missing and the floors needed to be cleaned better.
The size of the apartment is perfect for a short stay. Breakfast was very poor.
