The attraction is little known, but it was very pleasant to visit. A real cistern, restored by the owners of the carpet store. It turned out great and an atmospheric little museum to boot. I recommend
Be sure to visit this secret place in Istanbul! Even if you come to this city for the first time, you will be impressed by the communication with sellers of gizmos with oriental flavor, Turkish tea and coffee from the friendly hosts.… They will certainly tell you their secret!
I advise everyone to visit. The cistern is located under the Nakkash carpet store. 5 minutes from Sultanahmet Square and completely free! Just go into the store and in the far right corner there will be a ladder down into the cistern. Go through the store and go down, none of the store staff stops you. The cistern itself also houses a small but interesting exhibition dedicated to the history of the area.
