We had a lovely one night stay in Debbie & Gildas’s garden 'shed'!
Really nicely furnished, and a lovely comfortable bed.
If your breakfast routine involves more than a cup of coffee I'd advise buying something in. Crumpets didn't do it for us. We think a choice of cereals at the very least should be part of the deal.
And we are not sure how tall people would manage the bedroom. I banged my head a couple of times and I'm only 5' 3".
But overall - a nice place to stay.
