Book Claudio's place now if it is available - you won't regret it. This is the best airbnb I've stayed in! First, the apartment is sparkling clean (cleaner than a hotel) and is also a lot bigger than in the pictures (the kitchen in quite big, the bedroom/living room is spacious, and the bathroom is a great size with a great shower). The location in San Marco is perfect and the street the apartment is located on is also picturesque. I preferred being in this area as opposed to the touristy central area although you are still a short walk from the Duomo, etc. Claudio is an incredible host and he provides so many extra touches such as complimentary beer and a bottle of prosecco, leaving bottles of sparkling water for my first day of sightseeing, and having many snacks and candy in the kitchen. He also has a list of restaurants in the area and maps with sightseeing tips. One of his recommended restaurants is Fioraio Bianchi Caffè which is just around the corner. I went here for apertivo and loved it so much I went back a second night - it's a great place to enjoy apertivo amongst the stylish locals. Everything was so thoughtful and staying at Claudio's airbnb enriched my experience in Milan. Loved this place!
