We stayed with Valentina and her family for 2 nights, it was a very quick trip for us in and out of Milan in less than 40 hours.
She seemed very nice and helpful, her mother was also really nice and they're very kind and warm people.
However, the actual room does not resemble the photos on the listing. It was ok and the place was clean, but it was super cluttered with tons of stuff all over, there's even a pink swimming pool floating chair on top of the closet!
The bed was a bit too small for 2 people to sleep in, and we're 2 small people.
The bathroom was clean, but the shower drain is blocked, so you're showering with your feet covered in water.
Location was good and there are lots of shops and restaurants around.
We booked this the last minute and just needed a clean place to sleep and shower, so this was fine for the purpose. If you have more time you can certainly find a better deal for the same price.
