This is where we stayed for a week in Cornwall. Today we left, heading for home. It took all day to get as far as Gloucester so we ended up doing another overnight stay in Gloucester as I could face another 4 hours or so driving on top of the 6 I'd done already!
The roundhouse comes with a 'treehouse' as well containing a kitchen and shower room. This was a fantastic place to stay, highly recommended! I've shared some more photos of it in a blog post.
