Very centrally located, cute little apartment. It's just a short walk away from the metro and bus route which can take you anywhere in the city and a short (but steep) walk away from Taksim and Istiklal street.
There's also a supermarket across the street where you can buy all your essentials and a Domino's pizza a few meters away. Literally everything you need right at your doorstep.
Ridvan was very responsive to any questions and extremely helpful.
