They say that this village consisting of caves dug in a valley has been continuously inhabited for the last 3000 years. The population is definitely low here, they say there are just 60 people living here, and the old women sell herbs on the visiting tourists. The interesting thing is that it is a fully functioning town: there is a mosque, a town hall, even a hotel. And yes, if I wanted to stay here for the night, I could.
Anyway, I didn't. I just spent an hour exploring the caves. They say that Cappadocia in Turkey is similar, but this one is smaller, and definitely with fewer tourists.
