I enjoyed staying with Mehmet, his GF and lovely cat Bulut.
The room had everyting you ask for, nice comfy bed, desk and a closet. No traffic noise in the room which let you sleep in as well.
Location is realy perfect, just 3-5 min walking to Underground M4, central Bus stop and ferries!
SAW Airport buses (HavaBus and HavaISt) bring you every 30 min to and from the Airport to Kadıköy for 38 TL currently ~2 Euro.
I really enjoiyed staying with the guys and would honestly visit them again.
Going to miss playing with cat Bulut as well :)
