Gülcan is a very nice person. The apartment is modern and has everything one needs. And if no, just ask Gülcan, she will do her best to get you that. It was a pleasure to stay there. We definitely recommend her as a host.
The metro station was a bit far from home (2,5 kilometers), but the district is silent and gives you an opportunity to see how locals really live and to rest from buzzing Istanbul Centre:)
