Start by clicking the Hubs button in the left-hand menu, as shown here:
Then you'll be redirected to the advanced search page. Make sure to filter by the type of co-working space.
Search by location is recommended, so make sure that you filter for your preferred city! As co-working spaces are not usually tagged, there's no need to search by tags, like you may do when you search for companies.
Once you have the results you want, you can export them or save them to a Watchlist.
