Sannie's in Berlin for her year abroad, and I've been following her adventures on her blog. She finally moved into an apartment yesterday, which she was obviously psyched about. I can't wait to go visit her, I'm rather excited to see how Berlin's changed in the five years since I visited there. Plus it'll be nice to visit someone who can actually speak German. About all I know is airport ("flughafen") and train station ("bahnhof").
I am sure that you and sannie will have a great time together. She will take you to all the hip spot. I am so glad that she is having a good time over there.
