Thanks - I *did* start there ;-) Though I noticed yesterday that one I'd put on my map no longer is operating so I should go and look again, for new and/or to remove places that might have shut down - I started this research quite a while ago.

I also found a couple of specialized rental websites that filter by AGA (or Rayburn) stove availability, which is nice! I saw a property yesterday that had a thatched roof AND aga stove. I was looking at a couple of Norfolk tourism websites ("best birdwatching in England" keeps this area on the list for now, for sure!) and one site had a list of various big houses and gardens to visit, I think the site had churches as well but I started with houses - and they called out which were NT properties, which is helpful!)
