Nicola's place was exactly as described – a small studio (basically one room) in a building full of students and young people in a very central location. 15m walk to the Duomo, 15m walk to the canals. I booked on very short notice and Nicola was a perfect host! He was there to greet me even when I was an hour late and he let me check out an hour later too. Check in/out was seamless and overall a great crash pad for a solo traveler who wants to spend most of their time out on the streets of Milan!
