Once you’re checked in, there are free lockers available to use in the dorms. Bear in mind, though, these aren’t usually big enough for very large bags. If you can bring a smaller backpack which you can use to put valuables in and lock away.
Remember to bring a padlock or you can buy one at reception if you forget.
There isn’t much hanging space when you’re staying in a hostel, especially in a dorm, so we’d always recommend packing clothes that don’t crease easily!
Please try and be considerate to other guests too and make sure that your own clothes don’t take over the whole room.
