Marzio is very nice and available.
We had a very peasant surprise when we arrived because the apartment is in a gorgeous residence that we didn't saw in the pictures. It was really clean, well situated and comfortable. However it was a little noisy at night but nothing too disturbing. I highly recommend this appartement :) The situation is perfect, really close to Duomo (10 min by foot) and in navigli (our favorite district of our trip).
