Erhan was the most responsive host I have ever seen. He did whatever he could to make our stay pleasant. The only problem of mine was the stairs because I was travelling with my parent and a kid, it is mentioned in description that building has stairs but It was more than what i was thinking. The place is located very close to Galata tower and convenient for public transport. Just keep in your mind that the area is hilly (as most of Istanbul ), so if you are comfortable with that its totally recommended to stay here and there are lots on nice cafes and bars around.
