Stay here. If you have to live on two minute noodles for a month to justify it, then do it. The reviews for the barn were exemplary and for good reason - there is nothing to fault with it in any way.
We travelled with two children (5 & 2yrs) and had no issues with any amenities. Might also help that there's a cracking ice creamery 50m away from the barn...
Without question, one of the best places we've stayed on planet earth. Regardless of expectations - and ours were high - they will be exceeded.
