What are some spots good for studying? It's better if they're open in the evenings/weekends also, but anything is fine.
Here’s a list of libraries in Winterthur, and their opening hours.

You can sit in a cafe - I really like Kafisatz for example
Or maybe you can study at the ZHAW for Architecture. They have a nice library there
