Our tour was fantastic. Niki  had a family emergency but she quickly obtained a replacement named Matina. Matina was awesome.  We learned so much during our 2.5 hour tour.  If you are going to Corinth definitely ask for Matina...you won't go wrong.  

Niki is the perfect guide to visit Olympia with kids. We were in advance at our meeting so she started the visit earlier. We had a lot of questions so we finished later than agreed. Of course, her knowledge is vast (she's been interviewed for a tV documentary) but, on top of that, she's always entertaining, especially with kids.
