Erhan is the best host you can get. He was waiting for us for hours due to the delay of our flight. He sent us bunch of information about Istanbul, what to see, places to eat, hamam, shows, about transportation... He helped us when needed.
Apartment was clean, renovated in modern style while preserving historical elements.
There was shampoo in the apartment, dishwasher and tablets for dishwasher, washing machine and washing powder, enough cups, glasses, plates, bowls... anything you need.
There is also central heating in the apartment.
Location of apartment is great, few minutes to Galata tower, few mines to underground Sishane, a little bit more minutes to Galata bridge.
Neighborhood is peaceful and safe. Some grocery stores are few minutes away.
We really enjoyed staying in Erhan's apartment and in Istanbul.
I highly recommend you renting Erhan's apartment.
