CentralCleanSafe - this sums it up perfectly! We (6 people from Vienna) enjoyed the stay very much. Nice livingroom, nice kitchen, nice bathroom, 2 rooms with big double beds, the bunk bed in the third room is perfect for children. Great service, there's a lot of info material about the city, too. Very comfortable - feels like home!
We recommend Yeshim's place - it's a perfect base for discovering Istanbul's day&nightlife.
