We had overall a nice stay in this apartment. The location is close to the metro and central station, so it was easy to get to the Malpensa airport.
The aparment had everything necessary for a short stay. We also appreciated the information about closest restorants, supermarkets etc.
There were only 2 negative aspects:
1) the floors were dirty (probably hadn't been washed for quite some time, only dusted). The floors had dark tiles, so they looked fine, but we walked barefoot in the apartment and our feet were totally dirty afterwards. It seemed that most of the previous guests used outer footwear inside also.
2) the restaurant downstairs was quite noisy, so it was hard to get some sleep before 23-24 (if you are a light sleeper, I suggest to bring earplugs).
