Location near the key sites of Sultanhamet is excellent, however for us we were at the end of our Turkey holiday so choose this place for its relative closeness to the main international airport (took 30 mins during lunchtime). Our host provided excellent communication and answered all of our enquires promptly, we especially appreciated his support to complete/drop off our hire car and to organise taxi/s to airport. Also provided basic phone and Istanbul transport card for basics.
The place is quite small, including the bathroom and would be best suited to 2 singles, or one couple. Wifi is excellent and garden a nice outdoor space.
