You intentionally create a false impression of your rental object! Nothing could be further from the truth than your description:
"Please respect that building quiet hours are between 22:00/ 10:00 p.m. and 8:00/ 8:00 a.m. The apartment is equipped with a noise sensor...."
If there was a noise sensor it would have been triggered many times, not by your guests but by:
- Musicians in front of the building
- Garbage Truck parking and backing up in front of the building with extreme loud backing up warning beeping
- Street Cleaning Truck going up and down in front of the house for over an hour
Building Renovation works including:
- Truck with scaffolding keeps engine running in front of the building
- Dumping scaffolding onto the ground
- Construction workers hammering
- Construction workers fastening the scaffolding to the dowels
- Construction workers yelling in front of the windows
- Construction workers drilling holes into the walls
The noise from the renovation during the quiet hours between "22:00 and 8:00" was 95DB indoors and well above 100DB in front of the house.
Furthermore, the shower hose was broken and a picture fell off the wall.
