It was a short but amazing stay !
First of all many thanks to Beyazit who went above and beyond to help me with some issues (which had nothing to do with the stay), he was super friendly, great communication, fast to answer and gave good direction to find the place.
The studio had really cool decoration, much bigger than i thought and comfy bed.
The street and building were very quiet, and bonus, a view of the sunset on the bosphorus through the window.
Highly recommend :)
