Personal PROs:

-Everything is accessible, there are places working 24/7 so you can find food and etc.
-Room is cozy with nice lighting
-Nice and quiet neighbors
-fresh bed sheets with good smell
Cons:
-Kadikoy district was very noisy during my stay and i had to buy earplugs to sleep, but it barely helped, my sleep was distracted by street noise
-problems with shower and toilet plumbing makes their usage not so comfortable
-pets in the apartment were quite friendly but me personally is afraid of animals of any kind, so it was little bit stressing at the beginning
