Our other host cancelled last minute so we had to look for another place to stay in Istanbul. We were very pleased that Zeynep could accommodate us on such short notice. Communication was fast and good. The address was incorrect in the ad but near the real location.
The house has everything you need if you plan on staying outside more than inside ;) It looks bigger on photos but we did not mind this. Location is indeed super! What a great and safe neighbourhood to stay in with lots of bars, restaurants, cafes and other entertainment.
During summer we would not recommend it since it gets way too hot inside and there is no air conditioning (to get a fan would be our suggestion to our host). The house has few utilities in the kitchen, which is no big deal when you go out a lot but for example we missed some scissors. Also, two towels for us two was not enough. So keep this in mind if you stay for a while.
All in all, Zeyneps apartment is definitely worth the price and probably more amazing to visit outside of the summer heat.
