Here you will find a list of the things that weren't working/weren't as described, as you will see they are a lot so you do your math:
-first of all the communication was terrible, Frank never answered or when he did he was very late, so it was vert unuseful
-the address was wrong, not a problem, fortunately here in Germany people is very kind and we found our way back to the apartment
-the curtains were embarassing, they didn't even cover up the whole lenght of the window so it was impossible to sleep (it would have been nice to inform guests that they will not sleep because of the sun)
-it was dirty, and we had to buy slippers to be able to walk on the floor
- the fridge was not working, and when we told the host, and we received no response
-the microwave was not working too, to use it we had to push the plug into the wall
-only two of the stoves were working, it would have been nice to know that before getting it
-the pillows were horrible and fpr the whole stay my girlfriend had a terrible allery to dust, that she had to take antihistamine
-forniture was shaky, if you put something onto it, you risked it was going to fall down
-the wc was maleodorant, and the carpet and also the curtain in the bathroom were in poor hygienic conditions
