Classic design, easy to operate and clearly marked.
I usually don't make editorial comments about the overall hotel stay (this is about the shower controls, and the shower controls only) but I have to add that this was an excellent hotel experience. Highly recommended, especially if you are travelling with a pet.
I am most pleased that Nashville was able to offer you and Toofis some better-than-average accomodations. Myself, I was scared of slipping on the extremely well-polished marble floors and careening into the parking lot, but probably that's just me.
