Big and comfortable bed, the place was very clean, quiet, wi-fi and A/C working good, good location (15 minutes walking to Castle Sforzesco and 25 to the Duomo. If you mind walking there is a subway station very close to the apartment). There were plenty restaurants near, markets and pharmacy.
The only issue was the shower that took so long to get warm (but I believe that It was due to some technical problem). Despite that, everything was great and I would stay in Simone's apartment again.
