The appartment is very fine, and Carlo is the best Airbnb host we've ever met! We were very well looked after: at the beginning he provided us with snacks and wine, and at the end, when we experienced some health issues, he took us to the pharmacy and acted as a translator... We love this guy!
The appartment has a very pleasant, cosy atmosphere; we were a group of five, yet it was not at all crowded. Nearest metro station is a few minutes walk away, and it is about 15 minutes on foot to Milano Centrale station. The neighbouring streets are lively and interesting - it is really a heart of Milan (no posh at all, compared to the city center). The oldtimer trams are very fancy, but also loud - so take earplugs and enjoy your stay! We really recommend it.
