The place is an experience on itself. An old apartment building with the first floor repurposed for accommodation. It is quite an old but everything was fully functional and quite clean.
Berkan is a great host, quite friendly and easygoing, be it if you need someone to show you around or if you need some privacy. He was willing to help on anything...just ask.
The street may be loud, but still, its Istiklal. If you want some quiet time, go to a hotel I guess.
Considering the price, the place is a steal.
Highly recommended.
