Deniz was definetly way more than just a normal host. She took care of the transport from the airport to our flat and also the way back. At our arrival she welcomed us with coffee and really took her time to explain us everything we needed and booked us restaurants. The flat itself is simply amazing, it is very big with 4 big bedrooms and a spacious living room plus kitchen table, which we loved very much. The interior is so nicely made, we couldn't stop taking pictures from different corners of the flat.
The flat has a big kitchen with all equipment you can think of, a coffee machine, etc.
Our favorite was the cleaning lady, she came every day when we were outside, exploring the city, and at our arrival the flat was clean and shiny. There were fresh towels and bedding sheets, in case of need.
I can absolutely recommend Deniz and her flat, if we come back with a big group like we were in Istanbul, we definitely will book her flat one more time!
