Overall a good stay if you're visiting Istanbul for a few days.
Good view from some of the rooms, and good view from the terrace. Good views are harder to find in Istanbul than you might expect, so it's a pretty good deal for the view. The hosts are all helpful enough. They'd offer free tea and coffee on the terrace for example. The rooms are small, but sufficient and comfortable.
My only issue is the neighborhood. All the major attractions are very close, but the neighborhood is loud and pretty scammy. The neighborhoods north of the golden horn are much more pleasant and honest. But if you're only here for a few days, then this neighborhood is closest to the Hagia Sophia, Blue Mosque, cistern, etc.
Also there are really steep narrow stairs, jsyk.
