Sorry for the double post...
In Dielsdorf, the Hostpital (where I was born, lol

) has been transforme into an elderly home, or "Pflegezentrum"as they like to call it.
I still remember that as a Kid I liked to be at the Mühleweiher, watching ducks and enjoying the peace and quiet.
There is also a Sports-Centre in Dielsdorf, the "Erle". They have an Indoor & Outdoor Swimming Park, an Ice Skating Rink and some Wellness stuff.
But, at least during my time in the 90s, I experienced that the People there are very narrow-minded and judgemental. I hope and think that has changed, now that more people moved there. But I think there should still be a pretty village-like spirit to the people there.
Grewing up as a child, I can recommend Dielsdorf. But also if as parents you are looking for peace and quiet as well, and not the bustling inner city of Uster. Choice is up to you
Feel free to ask or DM me about Dielsdorf, if you like!
