Yasin and the others were really helpful. The place is really close to Kadıköy nightlife and the ferry to Eminönü. The place was alright, maybe a bit tiny and there isn't much of a view. However, you do get a kettle and a mini fridge.
I thought it was a bit overpriced. However, we just used the place for the night so it wasn't a bother. Apart from a bit of grime and rust the stay was pleasant.
