When I was looking for guitar few months ago, I did direct comparison of Olinda OC-300 vs. Espana CSR (you ask about CS which should not really matter). Same price, similar specs. Somebody played for me in the store. That specific Olinda sounded better, brighter and louder with better sustain. But it does not mean Espana is always worse. You need to try specific guitar to find out, not mentioning that strings (which were almost dead for both guitars in my case) can play a huge role in the sound.
I would say, for low budget beginner this can be a pretty good choice, better than laminated Yamaha, for example, but there is no guarantee that one specific guitar you get is good. Make sure you can return it, and go with it.
Your main concerns should be fretboard playability (especially low action without buzz), tone evenness, and proper intonation; you will need setup for sure. Many small stores who carry these guitars do not store them properly (temp and humidity vary ); inspect fretwork, body, and joints for cracks, slits, etc.
Good luck, and enjoy!
(still testing various strings with 2006 Sebastian Stenzel and Olinda OC-300)
