Lovely place in a good location - my partner and I were able to explore most of Milan on foot from the airbnb (most sights were within a 15-20 min walk away).
We didn't get to meet Marco personally but he was prompt and helpful in his correspondence. His apartment, with its knick knacks and quaint touches, was exciting to trawl through - but what came in handy was the well outfitted bathroom - with more soaps, shampoos and perfumes one could imagine at your disposal (certainly kept me smelling fresh all day long)
The apartment is on the top floor of the building - so be prepared to climb up several flights of stairs (it can be a struggle especially when laden with heavy luggage, but nothing too difficult to handle and especially useful for working off the extra calories from all that amazing Italian food)
