Convenient for Cologne, where I was at an exhibition. But hotel has a "dowdy" appearance due to very poor lighting. Those light bulbs that did work, did not flatter the place!
Bathroom sink impossible to put a plug in to shave, and had been built that way!
I bought through Hotels.com so price was reasonable!If I had booked direct, would have cost 33% more, and that would have been VERY bad value!
