The location is good. You are close to the Tram line, Galataport and Karakoy. It is short though (steep walk) to the Istikal street. The apartment is spacious, however on the 4th floor without an elevator. There is a good washing machine. I worked one day without any connectivity issues. The entrance doors are a bit tricky at first. Once you get used to there was no problem. The apartment was very clean. Unrelated to the apartment is that there are guys at the Tram stop selling overpriced Istanbulkarts (transit cards). They try to pass themselves off as being official, almost blocking access to the machines. They wanted 150 TL for a card that costs 50 TL. IMO you don't need a transit card as you can walk to the popular sights in less than an hour.
