Yes. HUSH lists 11 adults-only houses in Cyprus, each one with a minimum age of 18 written into its own house rules. They include The Ciao Stelio Deluxe Boutique Hotel, Madama Residence, 9 Muses Hotel.

The 11 Cyprus houses on HUSH are in Larnaca, Nicosia, Amargeti, Ayia Napa, Paphos.

One thing only: the house rules set a minimum age of 18 or higher — the rules a guest agrees to at check-in, whether they are on the hotel's own site or on its booking profile. It is not the booking site's adults-only tick-box, which the hotel sets itself, and it has nothing to do with adult content. Each page quotes the sentence and says where we read it.
