Myself and two friends stayed in this appartment for 3 days.
We found the communication with Saban and his colleagues to be extremely good - everything went smoothly including the pick us and drop off at the airport.
The appartment is quite small but fine for 3-4 people and the bathroom is done to a really high standard. It has everything you need for a short break.
The appartment was a couple of streets away from some restuarants and very near to the Grand Bazaar and Blue Mosque. We also got a taxi twice to Takism in the evening and it only cost us 15lira!
I wouldn't recomment for people on their own or elderly people but for me and my friends are a girls long weeked - it was just right.
