It was our first stay in Istanbul, and we were glad that we booked exactly this room! See view really means amazing view on Bosphorus ! Breakfast is included, what is good. The house is full of weird things and people, but we love it.
5-7 min walk from Sultanahmed square and Sophia mosque, 7 min from train station (T1) and airport shuttle (IST-20). 15-20 min from Grand Bazar. So the location is 5*.
Take a note, that every morning the pray starts and it's loud and unusual, so take ear plugs. Or don't - in that case you will dive into city's atmosphere.
