I stayed with my parents at my sister at Garen’s place for a week. The flat is really nice and very clean. Communication with garen was very easy and he even let us do a very late checkout without wanting to charge us more. The location is very near to Istiklal street, just a few minutes walking. The area seems to be a bit dodgy but we were often coming back home quite late and didn’t feel unsafe at all, there were always lights and people around in the street. I can totally recommend staying there!
