How would one ask "What sort of place is Wales?"
Sut le yw Cymru.
Thanks---I don't know why I thought it would be more complicated than that....
What about... "How was Wales?"
Sut oedd Cymru?
If you want to say did you have fun in Wales
Ges ti hwyl yng Nghymru?
Well, you see...
This feels like a rather artificial sentence. Does it mean "How was Wales?" (while you were there on holiday)?
Yes, it can, as in asking your opinion. Or it could be in a history lecture: "What kind of place was Wales (in the Middle Ages)?".
