Recommend Ettore's place as a great place to stay for a few days in Milan. It is very stylish and comfortable. We worked from the apartment for a few days and the WiFi etc was fine. Quick and easy check in with good communication with the host!
We knew that the area wasn't amazing but it was very easy to get to better areas using the metro. Don't be put off by being so near the train tracks like I nearly was, it wasn't noisy at night especially when you had the air con on!
