This was a nice touch, but we didn't need a towel warmer when the temperatures were in the 80s. (It's amusing to hear the local folk exclaim
"we're not used to the temperature being all the way up on the 30s" (Celsius, that is!). And the hotels & cars are not equipped with AC.
BTW, 30 degrees C. is equivalent to 86 degrees F. We informed our guests that we had a few days (in KY) at 99-100º the week before we left for Ireland.
