It's amazing how transformative a good, clean bath mat can be, isn't it?
Fresh flowers 3 of 8
It seems rather luxurious to have something as delicate as flowers in such a place as a bathroom, but that is just what I love about it. Pick a single bloom or bunch a humble clump of blossoms in a casual vase, and your guests will feel right special, as they should.
Dedicate a towel in their honor 4 of 8
I love the idea of color-coding your towels anyway, don't you?
Extra, stacked towels 5 of 8
Don't be stingy with the towels! The worst feeling ever is when you've just finished a shower in an unfamiliar bathroom and suddenly you are unsure of where the towels are and whether they are currently "claimed" by permanent householders. Keep a good stack of fluffly towels somewhere obvious (possibly even in the guest room?) and mitigate this pending disaster!
Personal shower kit 6 of 8
One of my favorite things to do is prepare a basket of shower essentials. I like to include travel-sized shampoo and conditioner, a razor, a fresh bar of soap, a loofah or bath sponge, and leave it on the guest bed.
Spare TP in easy to reach places, and make it soft! 7 of 8
Pretty self explanatory. Nobody needs to wonder where the TP is in a moment of crucial need.
Extra blowdryer, and other necessities 8 of 8
I almost never remember to pack a blow dryer when I travel, it is like some weird kind of brain block. Other commonly forgotten necessities? Toothbrushes, toothpaste, deodorant. Keep a couple spares in an easy-to-reach location and you'll win for Best Hostess Ever, no contest.
