Poor service, no air conditioning in 39c temp

Poor check in. Wanted to check in and go to a business meeting. Couldn’t get to one of the rooms as the key wasn’t working. Went down four times to reception and wasted 45 minutes and nearly missed my meeting. Hotel is not very clean. Air conditioning doesn’t work and when you ask for it to be fixed they lie to you and say we will get it to work which never happens. I travel every 6 weeks and I visited more than 120 hotels,”. This is the worst hotel I ever stayed in and I cannot believe it’s rated with five stars. I will never go back there ever again.

Temmuz 2026'da, 5 kişilik bir aile olarak 2 odada iki gece konakladık. Konaklamamızdan memnun kalmadık. Oteldeki her şey bozuktu: zeminler, kaydırak, kapalı havuz, kapalı oyun alanı, mobilyalar, duş kapıları. Saymaya devam edebiliriz. Ayrıca, hizmet de yetersizdi. Giriş işlemleri çok kaotikti. Kahvaltı sırasında ise çoğunlukla kendi aralarında konuşuyorlardı. Bu nedenle bu oteli tavsiye etmiyoruz.

Ortak kullanılan havuzun sisteminin bozuk olduğu söylendi, buz gibi suya girerek Termal tatil keyfi yaptık. Tek iyi nokta garsonların tavırları ve yemeklerin kalitesi diyebilirim.
