The location is probably the best that you will get in Milano. It is close to everything: the Cadorna train station is just a 10 minute walk, same for Duomo, Castello Sforzesco, Basilica di Santa Maria delle Grazie. The room is very small but it is ok. However, there is no fridge, the wifi does not connect on the 4th floor (it works perfectly everywhere else for some reason), the safe (although exists) is not fixed and can be easily taken away. The bathroom is really tiny, and it may be uncomfortable to stand in the shower.
