You make a deal with the a really nice internet cafe with a good connection. All the kids speaking in a foreign language going crazy over video games might be distracting (especially when school comes out o_O), but it's like a rentable AC office with a good connection and cheap drinks and snacks.

Or can rent a apartment that comes with it's own landline internet connection. The landlords can set it up in their name for you and it would be part of your rent.
