Thank you Adrian for letting us know. Nobody else among the eight people who has stayed here so far complained about it yet. Good that you mentioned it so we can improve. Apologies for the experience. We will definitely try to communicate with guest better in the future. Jakob and Hagen are co-hosts of the Apartment, so the hosting is done by one of us depending on who has time. This is stated in the listing.
Dear future guests: please take this into account when you make the booking if you are sensitive to noises. We would rather not to have the booking than having a bad review when we already try very hard to be a good host.
