Since I came to Istanbul for personal reasons, I have to start by saying that Mert was extremely helpful, which in general allowed my stay to be comfortable, otherwise, I feel like I would have been lost, taking care of what I needed to in Istanbul.
I stayed at the flat for a month. The flat itself is spacious, clean, and receives light from the large windows overlooking the garden. Since the weather was still chilly, heating and hot water were working fine. No issues with internet, washing machine etc .. and comfortable space to work off your laptop. Also you don't get any street noise. All in all a comfortable stay.
