I would say relatively low cost, you can get along with small amount of money if you want, thought you have to cut back for some luxuries then.
If you like sunny and hot, then definately amazing. i think there has been 1 cloudy/rainy day this summer.
No experiences from this one (luckily) but what i have heard basic health care should be free.
Very true.
I have not encountered any criminality yet, even late at night, so yea that should be true.
What i have understood tax % should be zero for maltese residents, and yeah its legal here.
I have no experience about thailand, but afaik westerns are more uncommon there as they are here, and get some kinda special treatment?
But yeah, im very happy here.
