Yıldız's place is clean, has all the necessary amenities and is really close to Sultanahmet area landmarks and places of interest. In the vicinity you can find small shops for food, as well as other stuff, like souvenirs and the famous baklava:)
The place is located near a bus stop and the waterfront, where you can also walk in the evenings.
Yıldız is very friendly and she waited for us to arrive at almost 2 am, due to a late flight. You can also communicate via wa.
Highly recommended. :)
