I'm sorry this is your experience with the apartment. Most of the guests are very happy with the location and have little or no complaints regarding the noise.
It is not a quiet apartment, although during the night time, it's usually very quiet.
Regarding the communication problems, all the information was passed to you prior to your arrival via email, key location and front door code as well.
On my side, the communication problem was that when you left, was the first time we heard of most of the problems you wrote about here.
I didn't know you where not using the front door code, where not using the hot water boiler (the dial near the shower, you just needed to turn it on), problems with cleanliness, towels ext.
If I would know that how you found the apartment is substandard during your stay, I would do my best to solve the issue before you leave.
This is true regarding all that was missing.
I'm really sorry for any distress this may have caused you, and just ask you in the future, make sure to let the host know of your problems when the occur and not in the review, as most of what you mentioned could be solved.
