Nicola's apartment is truly great. I've stayed there for 3 months but I'd reccomend it even for a shorter period. It's situated in quiet zone of Milano, but still close to city center (15 minutes by underground to Duomo), there are lots of bars, bistros and supermarket nearby. I've never actually met Nicola, but his parents are very nice and friendly. There was no problem in conversation with Nicola nor his parents.
