Hi janelondon!
I saw your posting on at least one othe other message boards.
You may find it difficult to get short term memberships at nearly any gym. Plus, you might have to show/prove local residency as well. You may be able to get a 1-month membership or a 2-month membership but doubtful for a 5-week membership.
And while I don't know of any gyms in San Sebastián-Donostia you'll likely have to wait until you touch down and then go to the local sports store for some ideas.
CLICK HERE for some In-Spanish possibilities and locations. Use the address to plug-in to
Google Maps to see if it's near where you'll be staying.
Best of luck!
Saludos, MadridMan
