We had a nice stay, definitely recommended. There is a nice restaurant right next to the apartment you can visit for traditional Milan meal.
The windows in the apartment do not insulate so good it can get a little colder when visiting in early spring or autumn. But it's really no problem because you can use the AC as a heater.
Also i would suggest bringing an eyecover for sleeping because there is a light that shines all night through the top window and it may be distracting to some.
