Güzeldi

Oda çok temizdi. Çalışanlar ilgili. Havuzda güzeldi. İstanbul’dan gittik. Havuzda temizdi memnun kaldık. İnterneti de iyi. Odanın ısı ayarınıda istediğimiz gibi ayarlayabildik. Otel çevresi sakin ve huzurlu. Başiskeleye çok yakın sahile. Sahile dolaşmaya ve kahve içmeye de gidin mutlaka.

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.
