Thank you. I realized that after I posted...doh ! I am not having much luck finding the Terre di Mezzo guidebook on Amazon. I can only find it on the website and it’s 17 euros for the book and 40 euros to mail it! I’m thinking I will be travelling sans book!
Good information about accommodation is available from the website and I really recommend the Sloways App. which is free to download... (But then I do have a tendancy to get lost... )
