My girlfriend and I stayed at this flat for a week. The location of the flat is perfect, because you can easily reach any public transportation from there. The flat also looked just like the pictures: very neat and pretty.
We felt very welcomed and could always ask the owners any kind of questions. They texted back really fast, so we never felt helpless at all.
They were always very kind and even booked us a Taxi back to the airport, because we didn’t know how to do that.
All in all, really nice, clean and pretty flat with a great location and service.
If you’re planning on visiting Istanbul, I would definitely recommend this flat!
