I concur with FlyingUndderTheRadar. Have someone you trust at home hold onto your items and send them when appropriate. Or, simply buy them while abroad.
If you absolutely must have your items, I'd try researching the Argentinian equivalent of the UPS Store. A local store that handles international shipping and local mailboxes will probably be able to accept packages and store them until you arrive.
If a hotel does accept it, I think there is a significant chance that they will agree to do it, plan to do it, accept it in good faith, diligently attend to it, and at some point due to the normal hustle and bustle of running a hotel, misplace or lose it.
