The flat was very convenient to our stay in Istanbul. It was on the fifth floor, there is an elevator to the fourth and some stairs leading to the flat. Basic equipement is available if you want to cook. Perfect for two people.
The only negative point I can mention is the proximity with the other flat, you can hear everything. But you can easily sleep at night, the neighborhood is very calm.
Both Taner ans Nicola are the best hosts you can find. Always smiling, answering quickly and flexible. I arrived two hours in advance in the morning and they still welcomed me warmly.
I highly recommend you to book !
