We have stayed during many years at your hotel in Hamburg
I was quite/very unhappy to get a room for 6 nights next to the elevator.
The noise might not be high but it disturbed every night, specially the thursday-sunday was quite busy.
I asked the guy in reception with chek-in, if he had placed os in a nice room.
and he replied , oh yes...
He should know better when we book 6 nights, it could be a problem.
and no, I did not complain, as I am not this type..
