It was a great experience staying at the Benan's flat.
Location is perfect for tourists, there are plenty of coffee and breakfast places around. And it's 5-10 minutes to reach Istiklal or Taksim.
Internet connection in the flat was flawless.
Cons:
- problems with warm water pressure in the shower
- couple of nail heads sticking out on the floor (it's old wooden floor, it's expected 🙂)
But I'm sure Benan and his assistants will fix any problem you have. Communication was perfect!
