Celia was absolutely wonderful – limiting the rating to 5 stars does not do her justice. Her knowledge of both the Opera Garnier and the Louvre was outstanding. And the time spent touring both locations was just right. We particularly enjoyed her tour of selected works in the Louvre and her insights into each of the those works. Her friendly, interactive style made this a memorable experience. We hope we can do another tour with her during our next visit. Thank you Celia SO Paris!!!
