Beautiful pictures on the website, but in reality it's in an uninteresting area outside of the city centre. That being said, it is very easy to access with a tram stop right besides the hotel and at only one stop from metro and metrobus. Quick access to the airport.
The rooms are average, the bathroom is dark. Not really nice, not really bad either, really average, probably not worth the 5 stars unless you get a big discount.
The breakfast is very Turkish (and excellent), don't expect too many western things.
There is a nice small swimming pool, sauna and hammam. The hammam is equipped with wash basins, and a heat stone. Towels, peshtemal and soap are provided free of charge.More
