Perfect place to stay to explore Istanbul!
Easy from airport-- take bus to Besiktas ( 18 Turkish Lira) then walk 15 mins. It is a steep walk up some hills so with luggage first time catch Uber.
The accommodation is close to lots of cafes and restaurants so excellent location. Close to public transport connections-- about 30 mins to Sultanhmet area and about 20 mins to Taksim Square which includes 10- 15 min walk to Besiktas bus stop
The room is clean, apartment well kept, drinking water was provided (tap water not recommended in Turkey). Shower runs hot with good water pressure
Lovely stay, would highly recommend
