I was there with my girlfriend for one week. The flat was very cozy and welcoming and we had more than enough space for us. The location was very good as it's not far from Taksim or Galata district and on the same time a pretty quiet and relaxed neighbourhood. The given information were pretty exact and the hosts Taner and Nicola are super guys and were very friendly and trustworthy. They helped us before and during our stay with tips and recommendations.
One tip for a good Snack/Meal around the Corner --> 'Tekin Kebap' had very good Adana Dürüms and else.
So i would definitely recommend this place !!
