Catharine is a wonderfull host. She helped us when we were in an unforeseen situation and had no place to stay. Thanks to her we were able to get a lot of pleasant emotions and relax.
The apartment are very beautiful and the view is breathtaking. There are everything for comfortable living and a big terrace when you can spent a lot of time because it's so cozy there.
Also the service is like in 5-stars hotels: you can have a breakfast, and food are in refrigerator and also you get a bottle of wine as a gift.
I recommend Catharine and her apartment. And when I'll be in Rome next time, I would be happy to stay there again.
But don't forget to close all the elevator's doors)
