I had a look quickly at the site but looks like the price is circa 2000 CHF a month and it is not clear for how long in the day...
If price is one of your drivers then I'd be careful since the krippes are typically about 2500 for 5 days/week/whole day (730-1830 or 7-19).
Other than that, being italian myself, I must say it sounds pretty cool and even think I will investigate more for my kids.
It is relatively new (end 2008) so maybe will be hard to find comments on it.
Lastly: if you are planning to stay mid-long term, it may be beneficial for you to think about local stuff in german as it will also push you and your husband to learn the language and make your integration possible/easier versus only navigating "expat world"
Ciao,
