The apartment is spacious and the bed very comfortable. The bedroom has a balcony and is very quiet. Doesn't seem that you are in middle of Istanbul. Cooked often, and there is everything you need to do so. Kitchen is small, neat and tidy. Location good for shopping, and accessing transport to the rest of the city. There are a lotof hills in Istanbul and indeed this is the case around the apartment.
Hazal is a really warm welcoming host. She helped me in lots of ways and kept me company when I was a bit lonely. Both her and her brother Kivanc are interesting, artistic, I really enjoyed chatting about films, travel, politics. The price is very good too. Highly recommended.
