I stayed one week in the appartment and had a good time All things were as promised from their website. The appartment was cosy and clean, not that big but just perfect for a single person. A big plus is the small balcony with a view to the local life in the narrow quiet street below.
The staff I met, was nice and very service minded, thank's for that.
I am now planning to return to Istanbul in the nearest future and will not hesitate to stay at this appartment again and will recommend to others as well.
