Ciao Ben!
IIRC, my PM for Neil was to ask for a place to sleep a couple of nights!!!
Anyway, the best thing you can do is to check
http://www.brionebouldering.com/ The access has changed now, and in the website they give you all the details. Bear in mind that one of the sectors will be closed to everyone from March 31st to October. I think that the other sectors remain open, but you'd better ask the webmaster.
There is one sector that is not featured on the topo, that is the river roof with Frogger etc. It's on the opposite side of the river from the other sectors, you have to cross the river.
Apart from this, there is no topo whatsoever, but if you follow the map it's very easy to find all the problems that you can see on many many videos.
I hope this helps, if you need more info feel free to ask.
P.S. Do you have a spare bed?
