I was thinking about Gardner House as well, but then I saw Snugpod, which had all six crafting stations as well as a transmute station, banker and de-con assistance. The crafting stations were in a circle around the room, and the transmute station was in the center. It looked like it would be a little better than Gardner House.
Stay safe
I use Snugpod for the free port back to Elden Root for turning in my completed Master Writs, but have also been considering setting up my own crafting hall with it. Glad to hear that it works because it would be disappointing to put in all the effort to set it up and find out it doesn't work!
