Deniz is indeed a super host: he gave us all the necessary information on how to reach his place with different means of transport prior to our flight, and he welcomed us on our arrival. The flat was very clean, the beds and sofa beds were spacious and the kitchen was very well equipped. Just as equipped as you would expect in your own home. For example, we were surprised to find a pressure cook in the kitchen which was very helpful for preparing food soft enough for our toddler.
The location of the place is quite centrally located on the Asian side and in direct proximity to a shopping mall and all kind of shops, restaurants and also a taxi stop. It is also in walking distance (~10 minutes) to a metro station.
During all of our stay, Denis was always kindly available for any query or request for recommendation that we needed .
For sure we will consider staying again in Deniz' place in any future trip to Istanbul.
