To keep it as simple as possible as I am not one to read nor write reviews, it was severely unpleasant. I didn't think it was possible for a 5 star hotel to be of such a low standard. Firstly, the rooms. Probably the biggest problem was the rooms. I cannot fathom the discrepancy between the photos of the room and the actual room itself. Everything just screams low quality, I'll get to the smell later. The shower in the bathroom didn't have a door or anything sort of barrier between it and the toilet itself, so as you showered water would spray all over the bathroom, wetting anything within the vicinity. Not to mention the room itself was incredibly humid. The whole hotel itself had a deepening smell of sewage, but that coupled with the humidity in the room was basically lethal. I couldn't believe it.
Moving onto the hotels facilities and such, they were great. It had a fun fair with many fun rides and enthusiastic staff. Great for kids. Not to mention how amazing the aqua park was, along with the multiple pools themselves. Now the beach on the other hand was simply futile. It really should have not even been there. The water was far too salty for one. You couldn't even walk in the beach as there were huge rocks everywhere, it's actually quite dangerous and I wouldn't recommend it to anyone.
Hotel staff were great all around. Really can't complain about them, the highlight of the hotel to be fair.
The weather is of course to be expected of Antalya. Incredibly humid.
