Kızımla haftosaonu tatili için gittim. Genel olarak idare ederdi diyebilirm. Oda temizliği çok iyi, ona lafım yok. Ancak restoran yemek kalitesine göre çok pahalı. Termal havuz asla sıcak değildi sadece bir kapalı havuzla aynı sıcaklıkta idi. Arabamı şarj etmek istedim, dışarıda 4 tane şarj istasyonu var ancak sadece üyelik kartı ile çalışıyor ve nasıl kullanılabileceğini bilen yok. Güvenlik resepsiyona, resepsiyon güvenliğe yönlendirdi. En son bilen arkadaşımız burda değil dediler, telefonla ulaşamaz mıyız dediğimde ise işten çıktı cevabını aldım. Valizimi taşırken yanımda küçük çocuk olmasına rağmen kimse yardımcı olmadı. Çocuk oyun alanı aşırı soğuk ve rutubetliydi, doğru düzgün oyuncak yoktu. En azından ısıtamaz mıyız diye sordum, teknik ile görüşüp mümkün olup olmadığını soracaklarını söylediler ama sonuç olarak ısınmadı ve haber veren de olmadı. Biz tatilimizi sorunsuz tamamladık mı tamamladık. Büyük b eklenti ile gtimezseniz mutsuz olmadan dönebilirsiniz.

Otel ve termal harika. Ancak otelden çıkacağımız sabah termale girmek istediğimizde bone olmadan giremeyeceğimizi tanesi 150 tl olan boneleri alıp o şekilde girebileceğimizi söylediler. bu otele 3. Gidişimiz ve kimse bize daha önce Bone takmamızın zorunlu olduğunu söylemedi. Bu oteli tekrar tercih etmeyi düşünmüyorum, daha önceden söylenseydi bonemi alıp girerdim ama normalde olmayan bir kuralı sırf bone satmak için zorunlu hale getirmeleri çok can sıkıcı bir hareketti. Tatilimizin son anını gerginlikle dolu geçirdik.
