The pilgrim accommodation in Vezelay is very nice - even after coming from overseas I would consider it. It is good standard. And they give you the space you need. Dorm accommodation though.
Accept their invitation to morning prayers at the basilica - it was one of the few religious experiences and highlights I've had on my way. With the monks, nuns and the priest of the community in one of the cozy old chapels of this ancient basilica.
I had lunch at the convent in Nevers. It is rather large and touristic place. Not so old. They where friendly and relaxed at the comedor. But I am not sure if I would like to spend the night.
Anyway, it's worth a visit. To learn about Sainte Bernadette. Pretty impressing and so recent. It inspired me to read up on her and Lourdes a bit more.
I can recommend the hostel from the municipality in Le Veurdre. Really nice and welcoming place (but no heating, can get really cold indoors). The village also has a bar, a restaurant, a shop, all you need.
And then the hostel APSJVV in Ainay-le-Chataux - small, friendly, with volunteer hosts.
There is an other hostel APSJVV in Bouzais, just outside St. Amand-Montrond. Haven't been there yet, but will probably stay there in September for my first night before hitting the road again.
@Katia: As I am messaging you in at least 2 different places: You are welcome to keep in touch also via inbox/messages. I'm fluent in English and also (or even more) Spanish, and French if necessary (but no Portuguese yet)
