Assuming you mean Valencia, Spain, I lived there for a semester last year, so maybe I'm a little biased, but it's an incredible city. If you're into beaches, they have some of the best there; though, I'd wager you'll have to try hard to find one not overflowing with tourists right now. You should definitely get out to the CAC (Ciudad de Artes y Ciencias), the new museum/aquarium complex with just absolutely spectacular architecture. Even if you don't want to do the museum/imax/aquarium thing, just walking around the complex and enjoying the architecture is a must. The best part about Valencia, however, is the old city. Plaza de la Reina is my personal favorite area - the famous cathedral and tower are there and there are great restaurants, vendors, bars, etc. As far as just pure sightseeing, get out to see los Torres de Serranos, one of the old gates to Medieval Valencia, and one of two left standing. The old city in Valencia is really just a great place to walk around. Make sure to get some Valencian horchata and eat paella (Valencia is the birthplace of paella, and still nobody does it as well as they do). If you're into it (I personally am not), Valencia has a pretty impressive bull ring for bull fights. If you or your wife wants to shop, Calle Colon has some (apparently) really good shopping. Valencia also has quite the nightlife - huge amount of good clubs and bars. Also, take a walk in the river; it's a dried out river that now serves as a park - it's a great place to walk and enjoy the weather. Lastly, if you feel like getting out of the city, there are couple places to explore just north in Sagunto and Peniscola, with Roman ruins and a Medieval castle, respectively.
