Superb location, very clean and curated to detail mainly describes this apartment, nice interiors and decoration, something hard to find in bebs of Milan.
The hosts keep in touch and responds quickly to messages and are very helpful, educated and gentle.
I stayed for 7 nights with my business partner and the size was ok but a bit tight, he needed in the last minute so it was a emergency resource, this apartment is best suited for a couple, or one person, so it is a compact place but well thought, and not a deal beaker.
Supermarket is almost in front, the Duomo 15 - 20 min walking, or two stops with the metro that is attached to the apartment, many restaurants around, the location is unbeatable, and a real joy. You have the S trains in the porta venezia station too, transportation is also outstanding.
Breakfast is not really included, but they offered small snacks and a bottle os nice wine :) .
Overall a joyful place that i would come back to and recommend.
