Yes, it was very nice and peaceful there. I live in the city now, so it's a lot busier and less relaxing! D:
With the phrase "I moved a couple of years ago", [I moved] is the action, and [a couple of years ago] is the time; that is, two or three years ago. 'Couple' refers to a small number, usually two or three.
I hope that clears it up a little!
