Great location and value for money. I was a little nervous beforehand about sharing an apartment but it worked out very well. I felt like I had my own privacy but Onder was available via WhatsApp to answer any questions I had (like when I got lost). He is a super charming host, speaks excellent English and provided lots of information about new restaurants etc. in the area. The flat was clean and warm and an easy walk from the airport bus stop.
If you're on a small budget and appreciate a host who knows the area and issues tourists visiting Istanbul can face then I would recommend this place for a few nights.
Thanks Onder; I didn't get the chance to buy you that beer but hopefully next time.
