heaven, haven

Heaven or heaven, according to some religious beliefs, means a place of bliss, a paradise where the good dwell with God after death--
"Our Father, Who art in heaven..."
"Imagine there's no heaven, it's easy if easy if you try..."

Heaven is also used to mean a state of happiness or bliss--
"Heaven, I'm in heaven, and my heart beats so that I can hardly speak..."
"Just Molly and me, and baby makes three, we're happy in my blue heaven..."

Haven or haven means a place of safety or refuge, as a small port or harbor for a boat, literally or figuratively--
This little inlet may make a safe haven for our boat.
The vacation cabin was a haven from the pressures of life in the city.

Now that you know that, you can say--
"After the pressures of  competition, the snug little haven seemed a veritable heaven on Earth."
