It was a great stay! Hamza's place is very well-stocked and has everything you might need and even more. It's in a close proximity to a large shopping mall, lots of nice restaurants and cafes, a Marmaray railway station and the ferries. The host is very friendly and communication was very clear and good. I stayed for 7 days but it would have been perfect even for 30+ days. If you still have doubts, please be assured it's a great find. :)
