Hotel is clean, modern, and quiet. The whole conception is based upon Turkish poetry, apparently. However, there is no attempt whatsoever to explain, clarify, or elucidate the concept in English or any other language.
All of this is not a deal breaker, but in addition, during our one night stay, the place was almost entirely empty. They have a "lobby bar" but it is manned by the busboy of the downstairs restaurant, who speaks no English and has no ability to make the drinks on the menu. They have a restaurant, but none of the staff can take orders or communicate if you don't speak Turkish. The breakfast was passable, but the woman running the omelet station had no understanding of what an omelet is.
The saving grace was a wonderful day clerk at the desk who could communicate perfectly and attend to our needs. She was there most of the time...
Our plan was just one night in Denizli. It was an overall OK city. We would advise looking at some other lodgings if you are planning a visit.
