This hotel was absolutely wonderful. The owner and manager was very hospitable and knows english well. It is so far the best place we (7 of us) have stayed in Turkey. If you don't have a car, it will be a bit harder to get to the top of the mountain, especially if you are trying to go to the south gate, which is much closer to the salt baths. We came in April, so it is fairly chilly, but the water is warm.
The hotel is very clean and professional, the beds are very comfortable, and the bathrooms do not stink like some other places. There is a soccer field and park right in front for the kids, there are restaurants, pharmacy, and market near by. Don't expect much from Pamukkale because it is a small city, but we were very pleased with the hotel. The food was good too.
