Marco's apt in Milano was a great base for us for our four day visit to Expo. Relatively quiet location a short walk to Garibaldi train station which is the best/fastest way to get to the expo. Marco and his wife published a guidebook and app about Milano which they offered us for our stay. Very helpful!
Nice having a kitchen and washer to cook and do laundry. Apt was comfortable. AC worked well when needed. Milano has plenty of mosquitos (even in the 5 star hotels) so make sure the included mosquito repellent is plugged in and turned on!
