My parents and I stayed at Murat’s apartment in the heart of Kadıköy for 10 days. The location is absolutely perfect, everything is reachable and either right before the house or within a few min. walking distance, which was the main reason for my decision. The apartment was clean and cozy, I would definitely recommend it. Murat was always helpful whenever I needed something and texted back within seconds.
During our stay there was a snow storm so Istanbul got colder than usual. Unfortunately the apartment didn’t have a heating system and we had to warm up the flat with the air conditioning, so it was a little cold at night. It can also get quite loud on the streets but that’s not related to the apartment and very normal for Istanbul, so I recommend bringing ear plugs :)
