I find the magazine "TIERWELT" really useful, it's amazing the properties you can rent or buy (available in any Kiosk). In one of the previous issues there was even an Aelpler looking for a housekeeper to spend a whole summer in his mountain hut for "Kost und Logis". If I wouldn't be married I would have been very tempted! There is also a website: www.tierwelt.ch
