Pros:
It was a great experience, smooth and easy check in and check out, location was great, accessibility to public transport awesome, view from the apartment awesome, washing machine was superb as we could keep washing, isitikal street is so close, Galata tower is at the end of the road, communication with host was great. Water was provided. Altogether we loved it.
Con:
Fourth floor as mentioned by host but be prepared to climb up and down 4 flights of a narrow spiral staircase everyday. Try to carry small and light suitcases. We had 3 large suitcases and 3 small suitcases. By the end of our trip they were heavy with shopping. So we hired a handy man to help us with the luggage down the staircase.
There are no start up supplies like milk, sugar, eggs etc. So go prepared with some groceries before you go up if possible.
