Luggage storage app

With the Radical Storage app, free for Apple and Android, travelers in cities in more than 70 countries can find locations nearby that will store their bags for small fees. Each bag stored with Radical Storage is insured up to €500 (near $592).

To use the app, open it on your smartphone or tablet and choose from one of the nearby drop-off locations that appear, then pay the fee, typically about $6 per bag per day, take your luggage to the location and show the code provided by the app. On pickup, the code must be shown again.
