Public transportation options are good enough, for sure. There is a station for Marmaray across the street; take the train and you will find yourself in the central Kadıköy in a few stops, or across the Bosphorus after a few more... There are options around for rental bikes, rent one and cycle the coastline to Moda (a beautiful neighborhood in Kadıköy) grab a coffee or a beer, enjoy the streets or the sunset, cycle back home; which was my favorite activity for almost every day I stayed with Ekim. The flat is warm, stylish, well-equipped and clean. The room is spacious and comfy. Everything was fine. And finally, there is this phenomenal host, Ekim. I don't even know where to start, you wanna meet her!
