Katerina is an amazing host - highly recommended.
Furthermore, she's an exceptional tour guide. We spent 2 days touring the island with her, and she went above and beyond any reasonable expectation.
She's basically a walking encyclopedia - language, history, architecture, you name it - she knows it. And she's more than happy to impart all that knowledge.
HIGHLY recommended, regardless of whether you just want a quiet time 50m from the shore or to dive head first into Greek culture.
Want to go lazy? Perfect. Eager for some culture? Just as well. We did both, and cherished every moment of doing either.
Thanks Katerina, hope to see you again!
