We had a lovely stay here. Apartment had everything we needed, including fruit juice, bread and pasta & sauce for first dinner, with a Carrefour mini supermarket just round the corner too. Really appreciated the air conditioning as Milan was roasting hot! About 10 mins walk from Moscova metro and right next to the park.
If you're visiting for the Expo, wear comfortable shoes - it's a long day!! Good and drink quite pricey but lots of free water fountains and free cardboard fans help - particularly recommend Angola, Brazil, Spain and Poland exhibits if you're going with kids!
