I thought our hotel was pretty cool being in caves, but, Kaymakli is a whole underground city that is so easy to get lost in. It is a huge network of caves that stretches for hundreds of meters. It goes underground for 7 stories and has a lot of living rooms and pantries and kitchens with ventilation shafts that go up and down from the outside of the cave all the way down to the bottom floor. I counted about 30 living rooms throughout the city. The guide said that up to 20,000 people lived down there if invaders came to their above-ground city. The weird thing was, we did not see any bedrooms, or bathrooms!
