We stayed for a week in Olga's appartment. It's location was ideal for us, 400m from piazza navona and only a few steps from very lively bars and restaurants such as bar del fico. However the appartment is tucked away in a very small piazza which is quiet and peaceful.
We saw all of Rome on foot and it really is an ideal location. The apartment is clean and very Italian with a lovely comfortable bed.
Olga was excellent, she assisted with cars too and from the appartment and gave us advice for local restaurants. She met us at the apartment and led us in on foot when the taxi driver couldn't quite find the square (like I said it's beautiful tucked away from it all).
When I return to Rome I will stay here again and I have no reservations in reccomending the place to family and friends.
