We had a really lovely time in gokalp flat! It was perfect what i needed, the room is clean, the bed as comfortable for us, and the space is roomy.
Nearby there is everything you need, a lot of supermarket, cafe and there some asian restaurant.
10 min walk you can see the shopping mall and marmaray train station.
Gokalp and the daughter very responsive, the communication and level of service will make your trip to istanbul delightful. Great host, great accomudation, great value. Thankyou
