I haven't been to this hotel, we were vacationing in the neighborhood.
There is a pier, all the sun beds are well-groomed, clean, there are no broken ones, there are portable umbrellas past the main ones, the staff will help you put them in the right place. The beach is pebbly, and there is sand. There is enough space, enough for everyone.
Pros: clean, there is a pier with a ladder for launching into the water. Sun beds, umbrellas are all in sufficient quantity. Shower, beach bar.
Cons: the entrance to the water is not convenient for pebbles and it hurts to walk on them. We were there for 10 days - all 10 days of the wave. The beach is not "childish" at all, a couple of meters from the shore is deep. There is no sand to build "cakes".
The sea is the purest. I was vacationing at Q Premium hotels, walking all over the beach. The pebbles are large, it hurts to walk with bare feet, and you need slippers. But if there is no such thing, you can also do it from the pier
