عندما تفتقد الحكمة تذهب لهذا المكان
Pros:

كان يعجبني الان لم تعد خدمتهم جيدة الماء الحار والمسبح الكبريتي لايعمل..

Cons:

الماء الحار والمسبح المعدني لايعمل
طلبت سرير دبل سايز لصقوا لي سريرين بكل غباء وسقطت بسنهما
لم يخبروني ان الماء الكبريتي لايعمل
موظفوا الspa سيئون جدا وغير مؤهلين لمقابلة السياح
الغرفة لم تعد نظيفة كما كانوا قبل عامين
كانت تجربة سيئة بمقابل مادي كبير
المكان لايستحق مطلقاً هذه القيمة

Pros:

Sehr gut. Da ist für jeden etwas dabei.

Cons:

Die Ausstattung ist etwas in die Jahre gekommen. Auf den ersten Blick ist alles sehr schön, bei genauerem Hinsehen offenbaren sich doch einige Mängel (Tropfende Klimaanlagen im Restaurant, Kaputter Türrahmen WC, halb abfallende Handtuchhalterung...)

Pros:

Recepciós nagyon kedvesek segítőkész.

Cons:

A klíma nem megfelelően működött, inkább csak ventilátorként fújt, és túl erős levegőt adott. És reggeli mindennap ismétlés.
