Pamplona hostels

I'm looking for recommendations and visitors' opinions of reasonably priced hostels in Pamplona during the running of the bulls festival. I want to book now in order to ensure a room when I arrive, but am fairly in the dark about which to chose and which one to contact that will be reliable and trustworthy in keeping my reservation.

While I don't think there are any reviews, you can find links to all of Pamplona's hostels which have websites @ http://www.MadridMan.com/pamplona/pamplonahostels.html . Hope it's not already too late to book a room! Usually the cheaper (and by cheaper I mean 2 or 3 times the normal rate) lodgings are the first to be reserved. Good luck!

Saludos, MadridMan
