I think this is the appartement you could get in the centre of milan !
It is a real smart automated appartement, very comfortable and functional. Everything you might need during your stay is there (soap shower gel coffee tea..).
Very good heat that is controllable from your phone app !
A little detail about the kitchen : there is only a microwave, no stove, but for short stays it's convenient !
The milan cathedral is a little far by walking but I am more of a walking person so it was fine for me,the central station is a 5 min walk from the appartement !
