Many years I coming to Istanbul. But this is the most clean, safe, non-hotel place. It is located in city centre. Place of many caffe, shops and the biggest transportation point of city.
It is never sleeping so may be noisy for you. But you easily can reach all greatest historical places of Istanbul, eat in perfect cafe and live near open minded people. My room was small-but I get exactly what i saw on the photos. Good equipped and very clean. You will be happy to stay here.
