Michalis has a very nice Studios-hotel/bar in Kalamaki on the beach (no road between both !). The studio was as described and clean, wifi works, etc ... The contact was very good (even if we stayed only 1 night). Michalis offered us a drink in his bar on the beach when we arrived. Kalamaki is a small village, dedicated to the beach, but quite calm, so if you are searching a place to do sea&sleep&sun it is a good place to consider. We found there a shop (in the same crossroad as the hotel) with local products at fair prices (and other gifts shops more "classic"). Of course I recommend Michalis studios without hesitancy.
