A nice and fair place in a beautiful neighborhood, a true dig for its price. Lacks natural light a bit, indeed - but hey, it's Istanbul, don't stay inside, go out and enjoy! Go elsewhere if you are feeling posh, but if you are in your adventurous student-y mode, check right in! The best neighborhood ever - close to the Galata Tower, shopping, restaurants, Sishane metro station is just minutes away, as well as Galataport which is downhill in walking distance.
Suleyman is a great and attentive host, always responds and you will feel welcome and taken care of!
