The apartment is clean and contains everything we needed during our stay. We didn't meet Ahmet in person but his assistant who helped us with every question we had. The neighbourhood may not be the cleanest, can sometimes be a bit noisy at night and has very steep streets (the walk to Taksim felt like morning work out to us), but we didn't mind so much as the place is located just 5 minutes walk from Taksim square and main shopping street Istiklal. All in all a good place to stay when visiting Istanbul.
