apartments are very comfortable - exactly as represented on photos ; self check in instruction is clear & detailed (i checked in around mid-night w/out any problems) ; central location in downtown: 1-2 min to shop / cafe / restaurants ; 5 min to main streets ; Ahmet - is very good host , replying very quick / asking how is everything going :) definitely recommend to stay; be ready - Instanbul is busy city , a lot of people on the streets day / night :)
