Onur place was great, we felt we were at home, the area is a bit noisy from the highway side, but the view is worth it.
Also the neighborhood is safe, the guy at the shop across the street was very kind and helpful, easy access to taxi and public transportation, 5 min to yenikapi metro station. You have shops, small authentic restaurants.
Onur is very responsive and helpful, me made serious efforts to replace the internet modem and now the flat has very high speed internet.
