At the very first moment, Efe Can was so responsive that I was able to book even around midnight. He replied all my messages in average 5 minutes. Unfortunately I didn't have chance to meet him face to face however his partner Memet made my stay comfortable through his simple introduction. I booked for 4 nights and then had to cancel my last day and Efe Can was very flexible even restored full day into my bank account. Shortly they are kind and decent guys.

Let me share my experience about flat =
PROS
+ The neighbors are good, they never bother you. If you are hanging out with your friends nobody will complain.
+ The location was very decent and secure so no issue to come home late or very early in the morning
+ It is very central location for taksim invaders > very close to any points in europe. Getting taxi also costs cheaper from Taksim to the flat
+ The flat is very clean, every day i was able to perform my morning exercises ( several push ups ) comfortably.
+ I could park my car just one street below called Dolapdere caddesi easily
CONS
- The street was too noisy so if you look for quiet place, this is not for you
- The outdoor is very complex so not easy to both lock and unlock
- The kitchen was too compact that if you will cook something it might be not easier
- The shower was too small either.
