I personally quite like Anvil, with the library on the middle floor and a pretty bedroom at the top, even though it's not very private. I quite like Chorrol's too, with the huge library, but I'm not so keen on the top floor.
I don't much like Leyawiin's guild hall, it seems too impersonal and the layout is a bit complicated, especially if you're trying to find a specific person.
So, thoughts?
