First of all I'd like to give the highest appraisal to the host. Mert is a very friendly, helpful, highly educated, open-minded and MINDFUL person. Staying in his place makes one feel comfortable and homie, and it's a genuine pleasure to communicate with him.
The flat is on the first floor and it has all the essentials one could need and even more.
The location itself is perfect. The whole neighbourhood is a middle class residential area, with lots of cafés, restaurants, various mini-shops, supermarkets, shopping mall... Everything is easily reachable: Bostancı Marmaray station is 7 minutes walk, so is ferry terminal and bus station. One minute more - and you're on the waterfront stroll along beautiful Marmara seashore.
To sum up, my experience as a guest at Mert's place was beyond expectations. I strongly recommend Mert as a host and his accommodation as a perfect option both for shorter and longer stay.
