We're wondering about Valencia as a holiday destination for us and our teenage son, in the summer holidays. Will there be enough to do? Is it nice? We'd be flying so we'd only be able to get to other places on public transport. We don't go for beach holidays but being by the sea for a city holiday is nice. Any thoughts? Or better suggestions for a good holiday place in Spain that's not high rises and bars? We've been to Barcelona or that would have been the obvious choice.
