The apartment is in a really good neighborhood if you're looking for a great variety of restaurants (breakfast, lunch and dinner) and bars, also it's very central as the next subway station is just around the corner.
It's not a very big apartment but as we just planned on sleeping there, it worked out fine for our family of four.
Tolga was a great host, he was there whenever we needed something, stored our luggage after our check-out and even brought us to the airport! All in all I can recommend staying here to anybody, you'll have a good time!
