The owner isn't very nice at all. There were three of us and we had booked an apartment for three and we'd paid for it. He told us "Not to expect the three room apartment". Our Tour Operator took care of him!
There are mice (or rats) in the apartment (between the ceiling and the roof).
The pool here is really nice and the rooms are really clean. We had plenty of clean towels and clean sheets.
This has been our worst stay in Greece (accommodation wise). Kefalonia is really nice.
