The entire experience was incredible and I was completely overwhelmed. Our tour guide – Maria was friendly, knowledgeable and professional. If anybody is planning to visit the Colosseum and the Roman Forum, they MUST do the upgraded tour. Being able to actually see the underground of the Colosseum and the third tier overlooking Palatine Hill and the Roman Forum is something I will never forget. Thank you Viator for making my trip absolutely magical – It was better than I could have ever imagined!
