On the plus side: It is very close to Taksim, it is safe with entry door and buzzer and double lock on the front door, with a small convenience store downstairs.
On the negative side: The apartment is very tired and in dire need of refreshing. The dishwasher, cooker and clothes washer don't work (or at least without some persuasion). The apartment is up 3 flights of stairs with no lift, not great with two elderly parents and 4 23kilo suitcases! This should be mentioned in the description. It is also within 50 metres of a mosque - again not mentioned. Finally, Taksim Square is very close, but up a very steep hill.
