Response from Jörg:
I wish you good luck for the next time when trying to find a room in a 4 or 5 stars hotel room at the center of Cologne for this price! :-) About the mirror- the apartment and everything at it is fully conform with the standards, and if a person is 1,90m tall one would see only his neck. You should have asked and I would've been very glad to help you and brought you a small ladder or a chair to climb on? :-) Perhaps you're right, we've had the same problem with small children, who didn't make it even to come on the brink of the basin.
About the washing machine- one can clearly see, this is a small apartment with a small bathroom and a kitchenette, so a washing machine and a dryer next to the bed is not the best solution, thatiswhy there is a washing room, which is typical for an apartment house such as this. It's the same to say at a 5 star hotel there was no swimming pool next to the bed :)
