In order to help the ones interested in following my footsteps, I'm providing the accommodation list I used. It is integrated with additional locations I found along the way, but it is certainly not exhaustive. In particular, in Castel di Sangro and in Lucera, many more accommodation facilities are available. Before traveling, check the Internet for further offers. If someone wants to communicate updates or indicate more locations, I will be happy to add them to the list. One more detail: I'm not in any relation with the housing managers so, please, directly address your requests to them.
