I've been coming to Istanbul for over a decade, but this was the first year that I decided to look for an Airbnb. I'd heard mixed reviews from friends who had tried this in Istanbul, but Elifa's place was ideal for me. The bed was very comfortable. Even though it was a little warm in July, I was very comfortable with just one quiet fan. The water heater (kombi) was also very good, and the shower and bathroom were very clean and functional. The location was also ideal for me. The apartment is about a 10 minute walk from the iskele (where you can catch ferries to Eminönü, Karaköy, Beşiktaş, and the Prince's Islands); about 10 minutes away from Marmaray stations (at Sögütlüçeşme and Ayrılık Çeşmesi); you can also catch the metrobus and the high speed train at Söğütlüçeşme. If you were traveling by HavaIst (the bus) from the Istanbul Airport or Sabiha Gökçen, that bus lets you off at the iskele - it's about 10-15 minute walk up the hill to the apartment. If you want to walk into the center of Kadıköy, that's about 10 minutes walk; but there are also a bunch of restaurants and grocery stores right outside your door.
In other words: A clean, comfortable apartment that is very convenient to Istanbul's transportation network and is located in a great Kadıköy neighborhood.
