So glad I chose to stay here. Massi's place isn't in the "heart" of Milan, but it's a small city and I walked nearly everywhere I went, so it's actually nice to be slightly removed from the louder areas. There's also ample public transportation nearby that can get you anywhere in the city pretty quickly if you don't feel like walking. It's worth the extra few minutes to get around for the value you're getting.
The apartment itself is cozy and has a bit of a hotel feel (in a good way). The room is spacious and there's plenty of room for all your stuff. The only drawback is that the WiFi was a little weak in the room – I couldn't get a great connection to FaceTime someone. Any non-video chat Internet activity functioned fine for the most part.
Massi is a very nice and clean guy and willing to help you with anything you need and give you local tips if you ask. Maybe my best Airbnb host so far!
