My husband's birthday is next month and I am trying to think of something to do for him. We are trying not to accumulate more "stuff" so buying him a physical gift isn't top of the list. Husband recently mentioned that he'd like to stay somewhere "really interesting" and gave examples like a converted windmill, or railway signal box with the features intact (like... levers or whatever).

I had the idea that we could book a little getaway somewhere like this and have been looking for unusual airbnbs or on Canopy and Stars, but other than one in a converted bus which was quite cool, I don't feel like I have found anything. The algorithm seems to think "has a hot tub outside" qualifies as 'unusual'.

Has anyone stayed in a really cool or unusual Airbnb or holiday home? Ideally in the UK as we are struggling this year to get time off work together.

Thanks in advance!
