Great location in one of the most vibrant parts of Istanbul.
Kadikoy is very crowded, full of restaurants, and can be a bit noisy. This apartment is located in the perfect spot, the calm neighborhood, yet it is a five-minute walk away from all the action. (Unless there is a Fenerbahce match that day, where you would need to properly plan).
The apartment is large, spacious, with lots of light in the living room and kitchen. I had two minor issues with electricity and the internet connection, and they were resolved immediately.
I highly recommend this place.
