Hotel is a bit off the beaten path, but that's not necessarily a bad thing. Don't rely too much in GPS or Google Maps, but th y will bring you close to the hotel and it is visible from afar.
Staff is good and IMHO, the best part if the stay.
Hotel itself has seen better days. Sky Bar, which was supposed to be on floor 11 was a horror show - pitch dark corridors with things on the floor.
They also hosted some event in one of their ballrooms. It was incredibly noisy and it lasted until dawn, preventing me and my wife from having a good night's sleep.
One good point goes to the breakfast buffet. Food was excellent and diverse. If you never visited Turkey this is as close as it gets in terms of good - meaning, it was tasty, diverse and plentiful.
Overall, it isn't a bad place to stay but noise was a bit too much for us.
