Looking for a spare room in Kilchberg

Hi, i am looking for a spare room for my aupair in Kichberg or area (Zurich Enge, Thalwil, Ruschlikon, Adliswil,etc) - not picky at all, since it will be for the nights only, she will be spending the whole day until later evening with us in Kilchberg.
it could be any type of spare room
thanks
Mariana
