I need some hotel advice. First timer to Berlin. I am interested in a hotel that is easily accessible to and from TXL via public transportation. I would also like something that is centrally located because I have less than 24 hours there and I want to make the most of it. Using Priceline is fine with me. Ideally, I would like to pay $120 US or less all-in, which may or may not be difficult given the atrocious value of the dollar against the Euro. I'll be arriving on February 16 and departing on February 17, 2008. Thanks for any advice.
