In a museum housing the donated private collection of what must have been a compulsive collector, the Koyunoglu (Sheep's son) Museum houses some fine, Seljuk, tiles, many good kilims and carpets, some Roman and other early finds, and a series of rooms kept in the old style in an adjacent building. I have often found that the museum did seem closed, but was open (even notices to the contrary notwithstanding), so try to get in. Give a tip for being shown the old style rooms.
This is a look in the old house next door.
