We had an overall fine experience but there were some things that need some improvement.
Good:
The host was accomodating and agreed to meet us for a late check-in around 9pm. The apartment is spacious and was fairly clean. It's also located in a central area close to bars, restaurants and anything you may need for your stay in Milan. The host provided clean towels, bathrobes, and a welcome kit of pasta and tomato sauce which was very nice of them.
Bad:
The main problem is the bed, it is listed as an old monastery bedroom but the condition of the bed is bad. It squeaks really loudly with the minimum movement so I had problems sleeping. It's also fairly small for 2 people.
The living room and bedroom both have big windows connecting to the outside but for some reason there is only half of a curtain set in each. This means you can't fully close the curtains so you don't any privacy during the day. In our stay they were doing some remodeling works in the building so there was scaffolding and we literally had people walking on the window level being able to fully see the living room and bedroom during the day .
We also couldn't find any toiletries so we had to do a supermarket run at 10:30pm so buy soap and shampoo.
If those things are fixed I believe this place could be s great stay in the heart of Milan for anyone visitinfor a short or long stay.
