Kalen is welcoming and friendly, I loved staying at his place and that he could provide all kind of tips about the city and places to eat. he is also very reactive, which was highly appreciated. I enjoyed a lot the appartment: its terrace, with the view on the galata tower. It is luminous and found it well located cos it's close to eminonu port (which can easily get you to karakoy or kadikoy) and to te metro stop Haliç. I work from home and could work there, when signal would be less good I'd go to the galata sahil cafe (14min walk crossing the brige with another fabulous view). I will miss my week there!
