Me and my boyfriend had a wonderful time in Istanbul and at Züleyha´s appartment.
She couldn´t be there because of work but her friend took care of us and was really helpful and gentle. Also the "american Girl" was a great roommate.
I would recommend this place to everyone who likes a nice, quiet place near all the Hotspots of Istanbul.
Close to Tram, Taksim, Galat-Tower.
And: Visit Limonlu bahce, best place around the corner.
