Zeyno's place is great if you are looking for a local apartment and a good "base" to hit the variety of Istanbul's neighborhoods and sights. The place has it's own unique design and spirit and Zeyno also made sure to equip it with informative information for us tourists. Besides that she and her co-host are super friendly and were able to give me great tips about the city. As a host, I learned a lot from them.
I would advice that some parts of the apartments are sort of a "hallway" to the apartment upstairs, which Zeyno lives in, so it's not a big deal, but still worth mentioning.
