Istanbul Hotel Ideas(Sultanhamet)

Derek

Does anybody here have any suggestion for an Istanbul hotel in the Sultenhamet district? My own research has created a short list and I am now looking for opionions on these or any other hotels in the area that people like.

So far the ones I like are:
Orient Express Hotel(not really Sultanhamet but...)
Obelisk & Sumengen
Valide Sultan Konagi
Spina
Mavi Ev(Blue House)

any thoughts would be greatly appreciated!!

Thanks
Derek
