The apartment war clean and tidy when we arrived. Also, the owner welcomed us very nicely as soon as we arrived.
Not only is the apartment located close to the Galata tower but also to İstiklal caddesi - in other words: the best location.
The only thing that was a little annoying was the Wi-Fi connection that was not strong enough for me to work from home.
Besides that a very good place to stay - I can only recommend anyone to stay there.
