I'm living in a tacky apartment, temporarily, so I am presently without a favorite room. In the past, however, I have loved strictly bathrooms.
The shiny porcelain, mixed with the fresh scents of co-mingling lotions and washes, feels amazing.
I love bathrooms almost obsessively. Everwhere I go, I encounter a new bathroom. An interesting facet, a clever soap dish, whatever it is, I will stare at it for hours, and love the owner a little bit more for having it. In fact, I probably love you for whats in your bathroom.
I love them the most when they are clean, with uniformly stacked towels in the closet. I love them when they are steamy; a temporary spa or a rainforest.
Bathrooms, when properly done, are a resort.
