Yasar was very reactive on what s app and answered all our questions very quickly even before we land in Istanbul. The apartment is located in the best area of Istanbul I would say....in a very calm nice street just next to Istiklal Street where you can have EVERYTHING starting from bar to museums and restaurants.
The only two comments to consider :
1) the apartment is on the 4th floor without elevator and the stairs are quite hard to climb (for those who have health problems or maybe old people)
2)The water debit (flow) was instable in both bathroom and toilet. Sometimes it gets very week during shower so even the temperature changes accordingly
