The apartment is really beautiful and cozy. Çok güzel! The newly renovated traditional house is amazing, with authentic tiles, wooden floors, and ceiling.
The neighborhood is a bit messy because this area of the old city was and is traditionally a shoe-making district. But honestly, it even adds to the authenticity of the place.
Also, it's very quiet at night. We slept like babies :)
10-15 mins walk to the Aya Sofia and the Sultan Ahmet Mosque, and many places to eat nearby, too.

Ilhan and Mrs. Gul who helped us to check-in were very helpful.
All in all a great place.
