Today Kelly's Korner's real life home tours is all about guest rooms. My parents live out of town and visit us about every 2 months. So, a dedicated guest room was important to me when we built the house. Of course, we would have given it up if we had a third child, but it turns out we were meant to be a family of four and have a guest room!
My theory of a guest room is to give guests just what they need. For me that means extra toiletries, including soap, q-tips, cotton balls, and lots of back-up t.p. (who wants to ask for that?!). I also feel like a phone, charging station, kleenex and a clock are a must. Other than that, I don't like too much in there. I say give them a blank space and empty drawers so they can unpack and stay awhile.
Here is our sparse, but comfy guest room. This is the original Pottery Barn Upholstered Headboard, called "The Lewis." The bedding is all Pottery barn f the same era with pillows purchased ions ago. The art above the bed was made from toilet paper rolls!
