My taxi driver couldn't find the street where the Apartment complex is located but dropped me near enough, bear in mind it is a hilly road. The outside might not seem appealing but inside is great, a steep-ish set of stairs when you enter. I was a solo traveller and felt safe in the area.The apartment itself was very modern, clean and comfortable and cleaned daily apart from Saturday. It has two TVs (with hundreds of channels!). A few noisy neighbours from the complex next door but nothing major. Nida is a great host and very helpful and informative about Istanbul, she gave me some very useful tips. The location of this place is fantastic and a 5 minute to the ever buzzing Istiklal Avenue which has so many places to eat and drink and you have Taksim Square on one end and Galata Tower on the other. You can get to the old city by Metro from Istiklal Avenue. Overall, an enjoyable stay in a superb city!
