Catrine's place is perfect!!! The location is amazing, right there in the heart of the city, next to Piazza Navona (my favourite square). The streets leading to the square are so vivid and lovely, we enjoyed walking in that neighborhood. The flat is spacious and very warm (important if you plan to visit during the winter). It was equipped with everything we can possibly need.
We had some troubles on the day of our arrival, we got robbed, so we were a few hours late for our check-in, but Catrine and her son organized everything and let us in the moment we finally got to the place and we are very grateful for that. Also, on our way out, they let us use the apartment for a few hours more and made our departure from Rome much much easier.
All in all, I can only heartwarmingly recommend Catrine's place. I hope you will enjoy as much as we did :) :)
