We stayed here for a week in July 2015. It was lovely to be picked up from the port to our lovely apartment in Santorini. Although we didn't meet Helen we kept in touch by email and George gave us many supplies of eggs and vegetables from his wonderful garden. The room was comfortable and spacious and we enjoyed our time very much.The nearby restaurants were wonderful and so was the pool and the beach.
You definitely need to get transport, although we walked the 4.9km into Fira and 4.9km back in the heat, it wasn't ideal and we ended up getting a quad bike for a few days.
The wifi was really good and still worked when we were half way up the street!
Thanks Helen for a great stay. We will definitely be back.
