We had a great stay. The apartment is very cozy and Garen is a perfect host, he even left us a welcome amenities. He met us upon our arrival and gave us useful tips about surroundings.
The location of the apartment is just amazing, just few minutes walking distance from the Istiklal street and close to Metro or Bus station as well as to the point of Havabus. (my advice never use taxi in Istanbul, use a bus or even better Metro, it is much convenient and reasonable).
I want to highlight how comfortable bed was, normally I have a sleep disorder but in Istanbul thanks to orthopedic mattress (I assume) I slept like a child. This is a big PLUS.
The surroundings are quite, no noise to disturb you.
