Lovely little apartment in a great location just 2 minutes' walk from Gerusalemme metro station. Well-equipped kitchen and bathroom (a combination of things provided by the host and those left by previous guests - everything from jam to biscuits to nailpolish remover!)
When we visited (late September 2018) there was scaffolding around the outside of the building, meaning that the window shutters couldn't be opened very much, but there was plenty of lighting in the apartment, and with the windows closed you can hardly hear any noise from outside, so we slept very well. Both the bedroom and the living room/kitchen have ceiling fans, and there is a fan in the bedroom, so we had no problem keeping the apartment cool (despite it being 30 degrees Celcius outside).
The area is pretty quiet at night and seemed safe to us, although there is a kebab shop on the other side of the road, so there might be some noise from that if the windows are open. Would highly recommend the excellent pizzeria Briscola on Via Piero della Francesca, less than 5 minutes' walk away, though booking might be advisable.
If we were to visit Milan again, we would definitely consider staying here again!
