The apartment is really nice and the hostel is really helpful, you will be beside most of the outlets like 212, Mall of Istanbul and Venessa, you need to rent a car to reach historical places but the location is far form Istanbul traffic...the pla e is really secured and no one enter without a permission, also parking is available
I would recommend this place for others who want to feel relaxed safe while they are in Istanbul, the hostel can also communicate in English and Arabic
