We used Eyes of Rome tour guides back in 2008 and again in 2019. Unfortunately we do not remember the name of our guide in 2008 but she was eccellent. Our last tour guide was Katie and she was so funny and knowledgeable. We enjoyed every minute of the Colosseum, so much passion, dedication and ove for her work. She also gave us a ton of recommendations for restaurants and bars and thinge to do on our own. 4 stars because they increased prices since 2008 :-)
