The studio is very nice and clean, however, it must be mentioned clearly that it has a window that goes into an air vent, it has no natural light or proper ventilation.
It has air conditioning, a comfy bed and other useful amenities.
It's 15 minutes walk to Sultanahmet, near restaurants and shops.
Some nights can be a little noisy and you can use some earplugs. There is a market shop near the building that it's open until late and has alcohol.
