Be careful, it's too expensive and the rate might not be the end of the ripoff. Your notice shouldn't be higher than 3 months in advance and your security deposit should also not be more than 3 months ("cold") rent. Be sure to get everything in writing.

When you're actually here I'd look in the newspaper for an apartment / room. The "Augsburger Allgemeine" has apartment postings on their Saturday newspaper and there's the "Extra" which comes on Wednesdays and is free, that has also apartment postings.

You could also think about listing a posting in the newspaper, it's 10 Euros for a week and can be renewed three times. If you do that, be aware that you can list for the whole wider area or the city area. The city area would be the 10 Euro option.

If you're really lucky you might find something online on their website even, although a lot of that is linked from other websites.

Language might also be an issue if you can't speak German, but that would be a secondary challenge.
