The Swiss might make their apartments of concrete with tile floors in all staircases, corridors and communal areas but this isn’t because the Swiss love to hear the sound of children’s singing/fighting/wailing echoed and amplified throughout their apartment blocks.
No it is not.
In Switzerland please be quiet. Not just on the stairs and communal areas, but please take care not to run out a bath after 9pm. It’s OK to run the bath, so long as you wait until after 8am to run out the water – God forbid that you run a dishwasher at night, and I am still unclear as to whether one can flush a loo in the evenings. I think once or twice is acceptable, just don’t go OTT. And hoovering is a complete no-no.
You won’t have to worry about the washing machine though. There will be a communal washing machine for all flats in the block in the basement which you will forget to book the necessary week in advance and so you will be washing your smalls in the bath. Just make sure that you don’t take the plug out after 9pm.
