I stayed here for a friend's wedding at the Four Seasons (5 min walk from the apartment) and would highly recommend this place!
Gherardo was extremely accommodating for our check-in / check-out times and the entire apartment was spotless. He was an overall amazing host and gifted us a nice bottle of wine, gave us great recommendations for restaurants in the area, and even called us a cab when we were leaving.
Note there is a washing machine but no dryer so you'll need to hang your clothes after washing (typical for italian apartments from my experience).
