Really, really, amazing location and an excellent apartment. The building is as central as one could be, just a few steps from the Galata tower, with tons of cafes and restaurants right at the doorstep and beautiful architecture all around. At the same time, the windows face the opposite side (overlooking a hill with a beautiful skyline view) and it's quiet in the evenings. The rooftop terrace is also pretty amazing in terms of the views, by the way.
The apartment is very clean, spotless and the hosts were super responsive. They helped us with bags and would respond at a moment's notice when we had questions for them. Definitely recommend this place for anyone traveling to Istanbul!!!
