Ilker's place will make you fall in love with Istanbul; don't think twice about it. You will want to sit in the living room and look at the Bosphorus all day. The apartment is super clean and cosy; you'll find all the basics of light travel (washing machine, iron, drying rack, etc.) right there. It is very well-located, with a tram station a 2-3 minute walk away and lots of restaurants. The only issue for some guests could be the number of stairs one needs to climb to get to the apartment, but if that isn't an issue for you, then this place is perfect. Can't recommend it enough!
