LemonLady, thanks for your quick and helpful suggestions. I do notice that most of these small hotels are south of the Blue Mosque so that the sea views are of the Marmara, not the Bosporus. If this isn't being just too picky for words, are there any in Sultanahmet, close to the main attractions, but also with that dramatic view across the Bosporus (but also with that high level of polish I tried to describe in my previous post)?
Once again, LemonLady, we're thrilled that you share all your knowledge and experience so freely. (And of course we'd welcome ideas from any and all others.)
