Hi again, Lepatriinu! You're right. There are few hostels on the internet in La Coruña, but I expect that will improve/increase in the very VERY near future. Madrid has nearly 80 on the internet and is far and above any other city/location in Spain - logically so, I guess.
You might try searching this forum (see link upper right) using the words HOSTAL CORUÑA as keywords.
Also, while I don't know anything about the hostels listed on the below link, there are 6 hostels with websites listed @: http://www.SpainHostels.com/links/Galicia/La_Coruna/La_Coruna/
Good luck! And please tell us which you chose and how you liked/diskliked it. Afterall, YOUR experiences benefit future travelers!!
for Barcelona information, Transportation, Lodging, & much MUCH more!
