Hi Tibo,
the hotel is located in Göynuk, about app. 10 km away from
Kemer. The beach is sandy, but the entrance to the sea is with pebbles, stones and sometimes even rocks. If you travel with children, this might be a problem.
I personally like Kemer, especially in low season and winter, when it's quiet, but not Göynuk. In Göynuk you just find some shops with fake clothes and fur/ leather and restaurants - that's it. No "real" city live like in Kemer. To me, Göynuk did not seem well kept, it was rather dirty. But of course you find more "live" than in Bogazkent
The hotel I don't know, just checked the reviews at tripadvisor... Many guests from east european countries -> ok, this is normal for the Kemer region. But the hotel staff does not seem to speak good english and the service also is not loved by everyone hmpf . After having read a few reviews, I'm not convinced and would recommend to watch out for another hotel. Of course the decision is up to you.
Best regards,
Sina
