The apt is very well located if you want to be central. It's 1 street from the Duomo. But Milan is small and we regretted not to have chosen another more quiet and less touristic area.
Also, we have been surprised by the noise at night, we could not sleep well: there is a tramway station down the street stopping every 5 mins until late...
Furthermore, the walls are very thin so you can hear the neighbors all the time (music in the morning, conversation at night etc).
Last but not least, the wifi was not working in the bedroom, only in the living room.
For the rest it was ok: the bed is comfortable, the size of the apt is quite big, lot of light and AC.
