Hamit is without a doubt the best host I had so far. The flat is great, it's situated in a hip part of Kadikoy and very close to all the ferries that will take you to the European part, but I would still like to point out that having Hamit for a host is what makes it special. He helped us out when we had issues with our laptop and called the shop where people barely speak English and organized a replacement power adapter for us. He was very helpful otherwise as well with recommendations and other advice. Thank you man!
