Grecotel is a BEAUTIFUL property! it has many pools varying for your needs. Its a kid-friendly hotel, but not designed exclusively for kids.
Of note, like many other beaches on the island, this is a rocky beach, water shoes recommended!
Also, if you do book on Hotels.com or a 3rd party site and don't opt in for all-inclusive, its worth exploring, as the hotel itself doesn't have much to offer since its situated away from most major towns.
