Overall this is a wonderful place to stay while in Milan.
Right at the Montenapolene Metro and a block away from all the famous shops. Walking everywhere is totally possible. The bedroom is a bit small for two people but the apartment is very comfortable.
As others have mentioned, it’s also at ground level which means you do hear the street noise but it was not a big issue while I was there.
My only issue, which the host tried to address while I was there, is the shower. The entire shower needs to be redone as there is red bacteria in the grout between the wall tiles. This made showering very uncomfortable. The host came to re-clean the area when I requested it, but I think the shower walls need to be replaced entirely.
