Did not meet Roberta in person but were greeted by her boyfriend at the apartment upon arrival. Roberta always replied really quickly to email/text messages and therefore communicating was very easy. The apartment is perfectly situated for the Expo, only two stops by train from Villapizzone Station. Getting to Downtown Milan takes around 35 minutes (Tram stop "Piazza Prealpi"). Really liked the Apartment, it's spacious, nicely decorated and very modern. We always felt safe in the area. Would stay again when in Milan.
