Our tour with Nina was amazing. Nina is very knowledgeable abut Greek history, antiquities and art, and was able to share that with us in a vary engaging way. We spent the entire day (8 hours) with her, exploring Athens and specifically the Acropolis, Acroplis Museum, the Roman Agora, the Plaka, the Parliament and Changing of the Guard, and the Greek Orthodox Cathedral, among other things. She is personable, fun and the tour was worth every penny. We highly recommend Nina!
