PS: Daniela, the person Katie Parla mentioned, is one of the most famous and qualified persons holding cooking classes in Rome. She trained in some of the most prestigious schools for chefs in Europe, now runs catering and teaches cooking from her home in one of the most spectacular historic neighborhoods in Rome. The question is, whether you'd be able to get her. People with her reputation are very hard to get. For example, just try to book a tour with Katie Parla, and you'll see what I mean. It's very hard to find people like her or Daniela to be free. You should reach out now, so that if she's not available, you can reserve other notable classes, before they're all gone. You're not going gonne able to tell the good from the bad from TrioAdvisor.
Remember, with all of the spectacular restaurants in Rome, TripAdvisor currently list a place called, "Bread-In" as the #1 restaurant in all of Rome. It's a panino (sandwich) store. You are always going to the bottom with TA, because you are asking for the opinion of people who have no idea about what they are writing about. The second best out of all 6,000 plus restaurants in all of Rome, according to TA is "Pane e Salame," a take out sandwich place. I don't understand why people would use it for advice. If you cannot get Daniele, there are plenty of other good cooking class options, but they won't be found on TA.
