Does anyone know any tips in terms of how to find a cleaning lady for a reasonable price in Lausanne?

 Basically, I will need her to come for a few hours to my apartment on a fixed date (only once) to clean when people who will be renting my apartment will be gone.

 Any advice / phone numbers / websites on this are very much appreciated!

 PS Would be great if she could speak English since my French is very basic….

 Cheers,

Maria
