5 star hotels poorly maintained?

Hey guys, this happened to me twice (once in 2024 and once in 2026), different places (Paphos and Protaras) to book a 5 ⭐️ hotel and when I arrived it was, well, to be honest, barely 3 stars. Is there some different system in Cyprus which enables the hotel to receive 5 stars without considering the level of maintenance and actual conditions on the premises (for example if rooms are bigger then 20sq m and has 3 pools - here’s 5 stars)? I’m really confused with what I’m experiencing.
