We stayed two nights at the Studio Principessa Clotilde in October and enjoyed it a lot! The apartment was very clean, nicely decorated and airy with large windows to the inner yard. The possibility to park our car in the garage was excellent and a great addition considering the location of the apartment - only a 15 min. walk to the Duomo. The kitchen was fully equipped and there was a big 24/7 grocery store just a few hundred meters away.
Fede was friendly and helpful, we highly recommend her lovely studio!
