Yunus was really friendly in conversations and answering fast on whatsapp to my questions. Thank you for that.
The appartment was quite dirty, the bathroom and kitchen, but not our room. But it was a pitty to sleep in wet, cold sheets because they weren´t dry when we arrived...brrr...
The place of the appartment in Besiktas is really central and close to public transport. That was great.
All in all, Istanbul is so beautiful so it was still a very nice stay!
