I came to Milano so many times and mostly stayed in hotels in center Milano. I have to say location wise there couldn't be any better than this apartment, in the center of Brera area, the happening place. Metro station is two minutes walk and within walking distance to many hot spots, even include Duomo.
I experienced two little problems with this stay. First of all, there was strong smell of painting that made me sleepless at night ( I believe this will go away after several months). Second, room is small and somehow the level of dinning room is elevated and therefore there is one step to living room and bedroom, which is not comfortable for me. Other than that, room is clean and the owner provides all the necessities there.
