The location in Brera is excellent, the check in was easy but maybe it would be nice for people to meet the host. Indeed, we know Milan as we lived there a couple of years ago but people would surely appreciate some tips.
The flat is big but a bit old and not really clean (sofa, dust on corners). The freezer was warm so impossible to buy and store gelati , the bathroom has a leaking tap which is annoying during the night, the coffee machine needs capsules impossible to find in a supermarket (online only).
People outside are partying until late at night, and it can be heard, but this is totally normal for this type of location. Anyway a nice stay overall, just a few minor problems, but the best location in the best city.
