We stayed in Marcello's flat for a week end in order to go to the Expo. The flat was really nice, clean and really well located (near the Navigli neighborhood), the metro station Porta Genova is next to the flat and there are a lot of white taxis near there also. We took 40 minutes to get to the Expo location. We got the keys from her nice doorkeeper. It's at around 30 minutes in taxi from the Linate airport. Marcello called and messaged me when we arrived, he's really nice host who takes care of everything :) There wasn't always hot water in the shower, there isn't a a shutter on the window in the principal bedroom upstairs. Otherwise a recommended place to stay in Milano!
