Valentina's place was great. Nondescript neighborhood out of the way of the main center, but only a 15 to 20 minute tram, bus, or subway ride to anywhere that you might want to go in Milan.
Coffee espresso, fresh milk, and biscuits were available, which was a nice touch.
Reminder for others to keep the water heater turned on for several hours if you need to take a longer shower, or if multiple people need to wash up.
Valentina gave an extremely detailed response about suggestions for where to go to eat and non-obvious sites to visit, so it is clear that she has lived in Milan for a while. Everything else went as expected.
Thanks for everything!
