The location of the appartment (in a very nice historic building) is just great to take a tour of rome. Having Villa Borghese close by was especially nice in the July heat. There are many restaurants close to the appartment and also a supermarket (open on sundays) just a few steps away.
Caterina is a very nice host and provided us with a number of recommendations for restaurants and places to visit. When we left some toys of our son in the appartment in a somewhat hurried departure, she was so kind to send them by mail, thanks a lot Caterina! Also Davide, who welcomed us in the appartment, was very kind and answered a lot of our questions on where to begin sightseeing in rome.
As mentioned, we stayed in July when it was way too hot for cooking, but if you plan to cook for a family you might find the kitchen equipment somewhat limited.
All in all, we enjoyed our week in rome very much, and I can happily recommend this appartement for your stay!
