Thanks to the internet I have some more information. Quoting from a site I found: This Mahperi Hatun Kervansarayı is located between Tokat and Zile. It is on the Tokat-Turhal-Zile Road which crosses the picturesque Kaza (Goose) Valley, about 1 km east (towards Tokat) from the village of Pazar, (so I found it using Pazar Han to search). It is built along the banks of the Yeşilırmak River and there is a Seljuk bridge over the river about .5 km to the northeast on the same road. It's from 1238-39. I found it closed but the entrance is great Seljuk art.
