Among the advantages: within walking distance from the port, good access to the sea, a DJ played atmospheric music in a local cafe.
Of the cons: it is very dirty around, not well maintained.
In general, having half a day of free time in the city, you can go for a swim after a walk.
The beach is dirty, like most public beaches in Turkey,
You can take 2 sun beds and an umbrella for 200 lira, the sea is quite clean, the approach is gentle and very shallow, there is a drinks shop nearby.
The average city beach is lousy. It's a little dirty, but the water is good and the descent is convenient. If you feel like it, you can swim. However, in order to have a human rest, I recommend driving out of town for 10-15 minutes. The sea there is wonderful and there is almost no garbage.
