We have had a lovely stay with my sister at Konstatina's place! The flat is very comfortable; the terrace is fantastic for evening wine and dinner, location is perfect, supermarket right on the corner, restaurants by the water nearby (you can see them from the terrace). There is a beach nearby, but another one, about 15min walk, called Almyros, is so much nicer and worth the walk (with a stopover for coffee at To Votsalo cafe.
Most importantly, the hosts are fabulous, very kind and helpful. We were greeted with homemade cake! I highly recommend staying at Konstatina's place. We've spent 5 nights and wish we had longer!
