Paola is a brilliant host, she gave us plenty of recommendations in the near area and was available on phone to answer questions during our visit.
The flat is wonderful, a lot more spacious than I expected from the images - and even though it is an attic flat, the building stays impressively cool in the hot Italian summer. The location is brilliant, you have everything on your doorstep (cafes, restaurants, gelaterias, shops) yet it's calmer, more relaxed than in the touristy centre of Milan. There are several metro stations if you want to avoid walking in the heat, but if you decide it is really nice to walk back from the centre (let it be the duomo or Navigli area).
