I would highly recommend Fabio's place. The two bathrooms were very clean, the beds are comfy and the kitchen was fully equipped. The house is only a 5 minute walk from the metro and the tram into the centre. We walked to the Duomo in approximately 40 minutes. The house is very close to the canals and nightlife, so it's really convenient for going out in the evenings. The entrance to the house is behind a gate which you can only access with a code, so it's very safe. Fabio was also great at giving us lots of information before our trip in relation to how to get to the house from the airport and things to see and do in Milan. He also arranged a taxi for us from the airport to the house. He's a great host!
