The garden room is delightful! We stayed 3 nights in November. It was a bit chilly as the bed is up against the window but that just made for more snuggling. In any other season I am guessing the room is perfect temperature-wise.
The bed is super comfy and your host family is a delight! They had great tips on where to eat and how to get around. Plus the mini-kitchen area is prepped for your comfort and ease of use.
Be sure to enjoy the cats and dog while you visit, they are super fun. All around a great place!
