Find cheap hotels near Istanbul Aquarium

"Room cleaning felt superficial. After first night my bedsheet and blanket had been turned 180 degrees for a reason I cannot understand. The area seems not very vibrant but of course the congress center is right there in short walking distance so that's the main thing. Overall very ok hotel but if you are expecting five star service this is not the place. Few minuses of walls being paper thin and AC only giving hot air. Plus for complementary water bottles in room. There was a fruit plate in the room when I arrived and after two nights the strawberry there was completely moldy and cleaning crew probably paid no attention to this."
