The flat is as described in the listing, clean and cosy, and it's located within a walking distance from the train station and several metro stops. It's in a well-preserved old beautiful building.
Josy was very accommodating, and provided an option to check in early - it was helpful for us, we could get a bit of rest after our flight before exploring the city. The flat had all the necessities: shower gel, shampoo, etc - even water and some food was provided. Josy has very thoughtfully put together some walking itineraries, and we took advantage of them; exploring Milan and its different architectural styles was a fun experience.
Overall, I can say that staying in this flat means staying with a host who truly cares about the guests, and I can highly recommend it.
