The host was really friendly and helpful. He help me to navigate the taxi driver from airport to home in the middle of the night and finding us a taxi back to airport at 4PM.
The room is also clean and the kitchen also complete and clean. It just 3 minutes walk to Taksim Square, and there are a lot of kiosk nearby if you need to by something to cook.
Really recommend it to every one and hopefully coming back if we visit Istanbul next time.
