Selim was extremely responsive and helpful, always there to make sure to that we have a comfortable experience. He arranged airport transfer for us at a very reasonable price, which was great because Istanbul taxis are hard to navigate. The apartment does not have a washing machine but Selim got our clothes laundered at no charge. The sofa doesn't convert into a bed but one person can sleep there. It's a bit stained though - it seems previous guests did not take care of it. Overall, the apartment felt a bit cramped and needs a touchup. It's on the ground floor, so there's no view and you can hear cars going by. It's only 400 meters from the Cemberlitas tram stop but it's a straight 30-40 degrees uphill walk. If you are young and fit, then you should be fine, but otherwise the location is not ideal. The neighborhood is just OK.
