HELP! Bike storage needed in Medellin after accident

Hi Everyone
We are are a kiwi couple who were just starting out on a year long adventure starting in Panama and working our way down to Argentina. Unfortunately yesterday, only the second day on our bikes I had an accident and have broken my collarbone bone, so no biking for at least a month!
We are flying in to Medellin from Panama City this Saturday night (Aug 20) and we're wondering if there are any amazing warm showers hosts that would be able to host us for one night and store our bikes and extra gear for a couple of weeks while I recuperate at a Spanish school in the mountains.
Any help would be hugely appreciated!
Kelly (and Michael)
