Clean and comfortable. Very very conveniently located by the central railway station. I had to catch a bus to Malpensa at 3:45am and only had to walk 5 minutes to the stop. It is also close to another less hectic subway station, if you don’t want to deal with the chaos at Centrale. The hosts were very responsive to my needs. Only complaint would be that the hot water runs out very fast. I don’t know if this is normal for Milan, but I did have to rush through my showers. It lasted just long enough to make it through at least. The bed (at least the bottom bunk, I didn’t have anyone on the top) was very comfortable.
