Hoshinoya, while not appealing to me personally, seems to be pretty highly rated. The Shigira (SLH) looks nice too, though also not really our thing. I'd use both "areas" as a base for exploring other properties as well. There are many lower and mid-range options to choose from, so you might want to post more criteria if you want to elicit a more helpful response from those on the forum who are in the know.
