Great place, location is fantastic - you can walk to all must-do things in Milan.
Wifi is fast and stable.
Elevator is almost ready so no need to drag suitcases up to the forth floor - we weren't as lucky as it's in the final stages of installation as I'm writing this.
Everything you might possibly need is in the apartment and Stefano is very responsive and helpful!
One thing to note though - it's very loud at night even with closed windows. So heavy duty earplugs are a must.
Highly recommend this place.
