After years on the app, this is my 1st review. The apartment and the host were so amazing, I had to.
I stayed in the flat for almost a month and I have lots of experience with longer-term rentals in Istanbul and I can tell you that this is definitely a gem. The location's absolutely perfect:
2 min from Akaretler's famous restaurants
5 min from Besiktas' center
10-15 min from the Saturday Market (fresh fruits & vegetables), the Bosphorus (with the ferry), and the bus station that literally will get you anywhere in the city
Besiktas is known to be a very young and alive neighbourhood but you won't be bothered by the noise at night or safety. Trust the pictures, I too thought it was too good to be true but no, and the place smells divine. I had no major issues and everything was absolutely clean and beautiful. Serra is absolutely an amazing host. She has been extremely nice, has helped me a lot and has been very transparent so you should worry about anything.
I absolutely recommend
