I really recommend Marcello's place. We were group of six while staying there and the appartment was more than suitable for us. It looks even better than on the pictures, and we really enjoyed our stay in Milano. Although it is not in the city centre, you can easily reach it by bus or subway. The main reason of our trip to Milan was EXPO, where you can get by the red line from nearby (15 min.) red subway line. The communication with Marcello and his mother before and during the stay was excellent and both of them were really nice and helpful. Thank you for hosting us.
