It does have one of the highest standards of living amongst
Central American countries, and is very stable politically.
It, as noted, has no army, but it does have a police force,
and crime is low compared to many other countries there
(but don't assume no crime at all; you will see the
standard security features, lots of locks and bars and
gates, etc.).

It's a very pretty country, with mountainous rainforests
in a country straddling both Caribbean and Pacific beaches.
San Jose (the capital) is in the centre of the country;
I haven't had a chance (yet) to go outside of San Jose
(I was there for work). I'm told there's good watersports
and diving on both coasts.

Enjoy your stay, and bring extra clothes. You might decide
to stay.

Cheers,
