Where can you safely store your belongings in order to travel? [closed]

As you point out, friends and/or family should be a consideration. If it isn't, you're typically left with self-storage. One example: Shurgard.

Much cheaper than keeping an apartment, but the costs do add up. If you only have a few suitcases that need storing, I'd try to find a friend.

Shurgard isn't the only self storage solution, but it's the only one I personally used. Their pricing schemes are somewhat obfuscated, which I found annoying. I used one of their storage facilities in the Netherlands for about two years. The first month cost me 1 euro, every other month was, I seem to remember, about 75 euros, all inclusive. Though I also had to buy a unique lock. This was for the smallest available storage unit.

Yes there are places that specifically provide luggage storage for travellers, but it won't necessarily be as easy to find them across destinations.

I was travelling at the time of the 9/11 terrorist attacks in Western Europe and North Africa and at that time many storage lockers disappeared for fear of people using them for bombs. I have no idea whether this trend continued.

I do know that in Sydney Australia there's only one place that still stores luggage for travellers, Travellers Contact Point. To give you an idea what the charges might be in an expensive travel destination:

ITEM                                DAY   WEEK  MONTH
Small Bag / Small Suitcase          $10   $35   $45
Medium - Large Backpack / Suitcase  $15   $40   $50
Surfboard                           $15   $40   $50

^{I tend to agree with MastaBaba; some more points.}

Helsinki, Finland nowadays has lots of temporary self storage options, and I'd be surprised if there aren't similar services in major cities in other countries. I suspect a big customer segment for these businesses are exactly people who go on a long trip and move everything they have in a storage for that time.

With little effort, I found at least these options in Helsinki area:

• Pelican Self Storage 1-3 m² starting at 30-111 € / month
• Oma Varasto 2 m² at 75 € / month
• Cityvarasto 1 m² starting at 32 € / month
• Suomen Varastot

Anyway, Helsinki is just an example (though it has a well-connected airport, it's probably not the kind of central hub you had in mind, and possibly more expensive than other parts of Europe).

I suggest you pick a potential city of your liking, and then just google: london self storage, berlin self storage, etc. Try e.g. this for Madrid or this for London.

As for more "creative options", I guess you could make friends with people on e.g. CouchSurfing and eventually come across someone in a good location with extra space in their house, willing to store your stuff for free or cheaply. Or you could ask around in CS groups of specific cities. Obviously this would require time, luck, and that you trust random people. I'd personally recommend just turning to a company specialised in personal self storage.

Go rural Hungary, go cheap: http://www.jofogas.hu/gyor_moson_sopron/Sopronban_5nm_es_tarolo_kiado_41472431.htm 5 sq ft storage 5500 HUF / month. That's 17EUR.

But I am sure it is possible to find a garage for even less in the countryside. If you are interested I will look.
