Avoid French cities: people constantly harass you for money and drugs and it looks shady and feels uncomfortable everywhere. Smaller towns can be nice.
And Italy: it's expensive, people are rude and arrogant and nearly every place I stayed at gave me a curfew so you can't even go out at night (but there's nothing to see there anyway).
Several hostels I stayed at closed at 10 pm and wouldn't allow people to go in or out
