Fabio is a great host! He is very nice and flexible. His flat was perfect for us, the Navigli area is not far away from the historical city center and it is a nice neighborhood with bars and shops.
The flat is great. Maybe a few things missing such as enough big towels for everybody (instead of small ones) and shower gel but this is really nothing.
We were 7 in the apartment and really enjoyed our stay. I hope we will be back soon!
