Word/Phrase of the Day: Ha dormido bien?

I look for daily opportunities, however, small, to use Spanish. If you don't live alone, this is one you might use:

Ha dormido bien? = Did you sleep well?

Note, there are those who might say "Dormiste bien" or some other phrase - I've been told that while this is very correct Spanish, it might seem a little old fashioned.

But hey, it works for me.
