I was extremely disappointed with my most recent stay at the Star Inn Hotel in Karlsruhe. They have switched to a free wifi service throughout the hotel, but to use it, a cell phone that works outside the US is needed, which I do not have. There was no option they could give me for doing this, even as I offered to pay for internet. On top of that, the wifi reception in the room was as low as possible without being completely nonexistent (which, altogether didn't matter, since I couldn't log on anyway). The air conditioning in the room sounded as if it were running, but the temperature wouldn't drop at any point. I make yearly trips here for work, and from now on I intend to stay elsewhere and commute for work, rather than being able to walk to work and suffer at this hotel one more day.
