Betty's place is fantastic! The studio is as spacious as the pictures showed (or even bigger), and it's very stylish. It is a short and easy walk from Stazione Centrale, and even though the neighborhood is quiet and not as vibrant during the week, it is easy to get around in Milan.
I didn't get to meet Betty but she sent detailed instructions on how to get there and Sebastiano helped me around. Grazie mille, Betty e Sebastiano!
