[QUOTE=Lrninnout;1601289]Can someone suggest a cheap decent hotel to stay at that is close to Artemis. Also, any info on what to do cellphone wise would be helpful. Can I rent one? Should I rent a car? [/QUOTE]Hotel. Discussed many times do search above on "hotels" eg Ibis, Kronprinz etc will come up, Berlin transit system so good not really an issue. Stay near Savignyplatz, or Stugarterplatz or near Zoo Bahnhoff, use Kayak or Booking or Priceline whatever suits your budget.
Car. Ridiculous to rent, use transit or bicycle. We're not in Kansas anymore, Todo.
Cell phone. Not sure what your question is. If you have a GSM quadband, you could buy a cheap local 15 Euro GSM chip and use locally as needed, to avoid non EU roaming reaming. If from EU country, phone should be affordable as is. US based CDMA phones will be a problem and you will face whopping roaming charges assuming (unlikely) it will even work. If really needed, you might rent one. But Skype or Google Hangouts an affordable alternative at a few cents per minute, with the caveat you have to be on Wifi to use affordably.
Of course, don't arrive without a copy of Herr Styles' Technocolor List of Lovelies and Damsels with Dorsals, to keep you on the straight and narrow. And practice on Kimino's Shark drone, discussed earlier this year. Really helps.
