Spyros and his wife Nektaria are simply adorable and their hotel is what you are looking for if you want to experience Kalamaki. They welcome you with everything you expect after a period of traveling (sweets and beers) and you can just relax by the pool before discovering the region.
5 min walks from the beach and the city center you will be delighted with this long beach away from more crowded places around.
Tiny negative point is the quality of the wifi, but it seems that the internet connection is not always good in this part of the region.
Thanks again Nektaria and Spyros <3
