The place is great! There are plenty of room in the apartment, convenient kitchen for a long stay, working area, chilling area, nice big bed. The place is nice and cozy, there are a lot of musical instruments. Wi-fi is working well enough to work remotely. The location is close to the main must-see places, so we could go pretty much everywhere we wanted by foot of using the nearest metro station Taksim.
However it is important to know that the traffic on the Tarlabasi Bulvari is busy, even in the late night, so it can be really noisy.
Hakan is the greatest host, he was really nice in communication, always replied fast, answer all our questions and he was waiting for us patiently, when we were really late to the check-in due to our flight delay.
So, our stay there was great!
