Having previously stayed at their sister property in Santorini, which fully deserved its 5-star reputation, we deliberately chose the same suite standard in Mykonos — a suite with a full pool and sea view — expecting a comparable luxury experience. Unfortunately, our stay at Katikies Mykonos was extremely disappointing and nowhere near the standard expected of a 5-star luxury boutique hotel. The most concerning issue was the lack of cleanliness and hygiene throughout the resort. We encountered cockroaches in the main reception area and even in food serving areas, while both pool areas frequently had crisp crumbs, used chewing gum, food remnants, and generally unclean loungers. Adding to this, the cushions from the sun loungers were simply repurposed each evening for seating in the champagne bar, often still damp and covered in sun cream residue — completely unacceptable for a hotel claiming 5-star standards. The suite itself was also poorly maintained. The shower regularly overflowed, and several bathroom fittings were visibly rotting. The hotel advertised a specialty restaurant on both its website and the in-room TV welcome message, yet it remained closed throughout our stay. We emailed multiple times in advance of our stay to book an airport transfer and to make a dinner reservation at the specialty restaurant. Eventually, we did receive a response regarding the transfer, but our request about the restaurant was ignored. It was only when we resorted to calling the hotel that we were informed it would be closed — despite it being actively advertised online and on the in-room TV throughout our stay. In reality, the only dining option available was the pool bar, serving the same very limited menu for both lunch and dinner, with few alternatives nearby. I had also mentioned numerous times prior to arrival that this trip was to celebrate my daughter’s special birthday, including her actual birthday during our stay, yet there was absolutely no acknowledgment from the hotel. Equally disappointing was the complete lack of recognition of our previous stay at their Santorini sister property. The private pool suites offer virtually no privacy, being heavily overlooked, and the overall atmosphere of the resort lacked the exclusivity and luxury expected from the Katikies brand. Finally, the check-out experience summed up the service levels perfectly: staff simply stated the amount due without offering an invoice or even thanking us for our stay, and then proceeded to ask whether we wished to leave a tip despite it being clearly evident from the bill that we had already tipped consistently throughout our stay at every transaction. While the Katikies brand elsewhere does indeed deserve its reputation and all accolades, Katikies Mykonos felt like a 3/4 star property at best. The poor hygiene, inadequate maintenance, lack of service, and misleading advertising cannot be overlooked .
