All in all, I would say the place was not great. Bear in mind that apartment is tiny, you don't have much space, but I guess that's what you get for that price since apartment/hotel prices in Istanbul is extremely inflated relative to it's GDP. The roomwas fairly clean, but sink in bathroom was completely clogged, so I couldn't use it at all, so I used shower room for everything.
Unless you're very tight on budget, I wouldn't recommend the place.
