Le Marche is less well-known than Tuscany or Umbria, but just as stunning. The local people are fabulous - generous, helpful and welcoming. There are several million bed and breakfast setups - almost all run by ex-pats who saw someone do it on TV and think it’ll be a hoot.
If you need a good B&B in Le Marche try Patrick and Enzo’s place: Mulino Barchio - they’re mates but I’d recommend them anyway.
