Wide beach with fine sand with enough space esp. in the far south or north, away from the main street. - Special prices for umbrellas and sunbeds incl. showers are right north of the big rock at restaurant "Theodorus" (nice place to eat, too), or beneath ask for COSTAS.
The beach is excellent but if you prefer a swimming pool there are plenty around that give you free sun beds with umbrellas and free use of the pool. All they just ask is that you buy your food and drinks from them while you are there.
