I want to go to France for a week. I want some sun/heat markets and nice coffee shops/ eateries . Going on my own and just want to potter. All the better if there is a pool. Any recommendations for an area that's not to remote would be appreciated. I'm UK so can fly into somewhere central and train from there. No driving though. Thinking Nantes/Nice but not sure about markets in these areas. It will be a last minute thing and in the next few weeks . Any suggestions welcome? Thanks in advance.
