I can only confirm the other comments - Marina's place is really beautiful, very clean and spacious in a good central location (even the building impressed me) yet quiet. The hostess always responds very fast to all your inquiries and together with her husband is very helpful in organizing your stay in Rome. She'll also arrange a taxi service from/to the airport (for a little lower fees than elswhere). I definitely recommend the place. Thank you again Marina for everything :-)
