Nice little apartment which plenty of privacy and actually and interesting view on an old building. One can easily reach Taksim square or Istiklal on foot. The Kabatas pier can also be reached within 15-20min walking. A nearby supermarket is Carrefour on Siraselviler Cd. Our host was polite and responsive and tried his best to fix the problems we encountered. The apartment was nice warm and comfy ,but the water temperature was not ok. The host tried to fix the problem, but it was just a temporary solution, as the the problem was (I am pretty sure about it) with the warm water heater itself (being a little old maybe and needing some extra maintenance). Another minor issue was the bed, which had 2 single mattresses instead of a double. This can be annoying if you are staying there as a couple, because they will constantly move apart.
Nevertheless we had a good time here and would gladly come again if the 2 said things will be fixed.
