This local expression can be interpreted in many ways, but it roughly means “this is living!”. (click the link above for more information).
I spent five or six months in Costa Rica quite a few years ago. I enjoyed spending time there and met some wonderful people, both locals and expats like me.
The pace of living is slower, the cost of living is lower than North America (although they have dual pricing on things/services. If you’re a gringo, prepare to pay more than locals).
