Eminonu’s apartment is located in city center, walk 10 minutes to Istikal street, as a matter of fact, I was able to walk to Galata bridge on my first day arrival.. Eminonu was very kindly let me check in early on my day of arrival. He respond to the messages. I can tell that he is a experienced AirBnb host that he knows what you need. There are several supermarkets nearby, the one opening 7/24 is about 2 minutes away. The apartment is small, but it has all the necessaries. I managed to stay here for 6 nights without any problem.
