I was in Milan for work, two-day conference and a visit to the Expo.
Valentina was very helpful, even texting me detailed instructions to her place when I arrived and technology failed me on arrival day (from Linate). Her home is very clean and comfortable and you have your own bathroom. The location felt safe and it's in a well-looked-after gated apartment complex. There's a park nearby where families hangout and children play into the evenings. There were several supermarkets within 5-10 minutes walking distance (there's a big Carrefour on Viale Espinasse that's 10 minutes away). Transport access into the city centre was super easy with tram lines no. 12 and 1 just a couple blocks away on Via de Panicale (about 30 minutes to Duomo). There's also the faster trains (S5, S6, S11, S14) via Milano Villapizzone (which is just 2 stops from the Expo or 15 minutes to Reppublica going the other way where you can change onto the M3 metro line) and the no. 90 bus that travels around the ring road (Circulare) -- a direct way to Milano Centrale train station (although at certain times of day, you'll be standing with your luggage). All in all, staying at Valentina's made for a lovely, relaxing trip -- a calm place to come home to after a busy day of meetings and conferencing.
