Can a Devon Rex be happy as the only pet in an apartment?

I'm thinking of getting a cat and like the Devon Rex. I have done extensive research on the internet and even talked to some breeders. The cat would be alone in the apartment during the day while I'm at work. I have read they don't always like to be alone and can even be bored and destructive if alone too much. Having two cats would be too much I feel. The apartment also has a balcony. Could this be a problem for a curious Devon? Any other advice I should consider?
