I would say it is terrific, wonderful. I would be full of energy after taking a nap during my break. Especially after a hard day of work or study, taking a nap in the afternoon, then I would be refreshing at that moment. Besides, I would stay in a good mood as well if I could take a nap during my break, it seems better than listening to some music or just playing some computer games during my breaks. So, that is it.
