This is beautiful. Very romantic and elegant. I know it`s sung in Spanish /and the song sounds great in this language/ but it could as well be sung in Italian and sound as beautiful. Love it.
Especially this line:

It was a pleasure to have your pleasant company,
But that hurts that it was something temporary.

Fue un placer tener tu grata compañía,
Pero que lastima que fue algo pasajero.
