Mert's place feels like home away from home. It's definitely one of the best places to stay in Istanbul if you are on a low budget. His apartment in Bostanci is clean, secure and just a walk away from the the bus station or ferry which would take you to any part of Istanbul. You can get to Taksim very easily. Mert pays attention to you, he understands your needs and goes beyond the usual to assist you. I would have missed my flight if not for him...Am really grateful Mert!
I'll definitely stay with Mert again when next I go to Istanbul.
