Things you need to know:
1) Pamukkale is a village, not a small town as I had originally thought. It's main attraction is the Hierapolis, and the famous white travertines. Most tourists tend to stay in the Denizli, then make a day trip here.
2) Hierapolis has 2 main entrances, one is the original entrance to the city, the other accessed via the travertines.
3) The Beyaz Kale Pension is located a mere 200 metres from the Travertines entrance, so in terms of location its excellent.
4) The Beyaz Kale Pension is accurately located on Google Maps, and will lead you straight to their main gate. Take it from someone not from Turkey who drove a rented car at 10pm to it with my sole reference being my phone.
5) There is free wifi in the rooms, and breakfast is complimentary, as well as home made.
6) The owner speaks basic english, so communication is not entirely a problem, and I was able to convey my requests with relative ease.
I had a wonderful stay with Uncle Omar Shariff (Yeap that's his name, though I took liberties with its spelling) and his family. He offered me a larger room for the same price because the smaller one that I had initially booked had not been cleaned yet. I was able to request a later breakfast due to my long driving hours each day. He was also willing to let me check out later since I wanted to rest again before heading out to the travertines.
The room itself felt like home, and had everything I needed for good night's stay. And with its location so close to the travertines, it was the perfect choice for me. Highly recommended!
