Barbaros' place was perfect for us, two couples and one child, exactly like in the pictures. Fully equiped with all you need and very comfortable.
Barbaros is extremly kind and help us with everything we had need, informations, parking for a big car, money exchange, papers for highway, local atractions and even gave us discounts and free lunch at his own restaurant.
The place is situated in old historical centre, walking distance to lots of attractions.
Highly recommend it to anyone visiting Istanbul!
