I was only in Milan for one afternoon/evening before an early morning flight. It took 10+ minutes to find this place once I arrived on the street, as the sign and address number weren't very conspicuous. I knocked on the huge green door, and someone opened up a smaller door within the door. I was greeted warmly, checked in, and was even helped up the stairs with my heavy suitcase. Room is small but totally sufficient. Bathroom is shared, but was modern and functional. Some of the lights are motion sensor, which was a little confusing, flipping switches and nothing happening. (The bathroom light did shut off mid-shower, but not a big deal.)
The front desk guy also gave me good info on how to get to Linate airport. I ended up walking the few blocks from hotel to Piazza del Duomo to the taxi queue. Even at 5:00 AM there was a taxi waiting there. It's only 15-20 drive to airport, and taxi cost 28 or 30 Euros.
