Thinking of Visiting Valencia

I am starting to plan my upcoming Spain trip for early October of this year. Beside coming back to Madrid I want to visit another city. So I thinking about Valencia and if do visit Valencia it would be for 3 or 4 days before I move on to Madrid which is for entire week visit.

From my research so far the things to see and photograph are:

- City of Arts and Sciences day and night

- The Old Town

- Valencia Cathedral

- Mercado Central

- The Silk Exchange

- A daytrip to Cuenca

I think MadridMan visited Valencia years ago and wrote about it?

Anyone what to give me advice or other suggestions about this, it will really be helpful.

Thanks
Bill
