I stayed in Pietro's little apartment for 3 nights, and there is absolutely nothing I could complain about. I was warmly welcomed by Daniela, Pietro's mother, who was very helpful and available throughout the whole stay. Also, I was very impressed how well equipped the apartment was regarding kitchen equipment and food (pasta, oils, breakfast bread, jam, cookies etc.). The studio flat is located in the very nice and lively neighborhood of Zona Tortona/Via Savona, with a lot of bars and restaurants, and in close walking-distance to the popular Navigli district. Also, the communication with Pietro was very easy and accommodating concerning check-in/check-out times. All in all? I warmly recommend a stay in Pietro's and Daniela's apartment!
