Me and my wife stayed only for one night as a layover on our return from Florence.
The apartment is housed very near the Duomo, which makes it ideal for sightseeing. It is a very beautiful and cozy apartment, extremely comfortable and modern.
Marilena was extremely helpful, leaving us a bunch of tips on what to visit in Milan in such a short time as well as being very open to helping with restaurant reservations and the like.
All in all, when we go to Milan for a longer vacation, I hope we will be able to book her apartment again!
