Farzin is a really nice person and great host, the check-in was perfect (althoughIwas late ). The room is clean, and sunny.
Internet speed is good, never had problems. Another benefit is a small nice kitchen where you can easily prepare the meal.

Also, the room has a small nice balcony.
The apartment is located in a good area, within walking distance from Taksim Square where you can find metro stations, bus, and all kinds of shops.
If I'm back in Istanbul, I would definitely stay here again:)
