The beach is also one of the longest in Greece. Every bar has a free wi-fi and you will not pay for the bed and the sun umbrella if you buy something from the bar, for example beer, coffee or cocktail. Very quiet beach, not crowded i recommend for families and for couples. If I am not mistaken, this beach was also awarded a blue flag, which speaks for itself. I love Sarti because during the day is very calm but night there are lot of bars and night clubs. But summarizing Sarti is not a party place rather rest place.
