How to tell if you've had a good night's sleep
I saw the above at medicalnewstoday.com
Please explain the use of "a" before "good night's sleep.
Does it refer to "sleep" which is uncountable?

    'Night' is countable. "I slept badly for five nights." But anyway 'sleep' isn't always uncountable.
    "Have you had a good sleep?" "All I need is a long sleep."
