I have been a member at Kiez Büro Coworking since 2018 and have been working primarily at this location since the space opened in the Brunnenviertel in the summer of 2021.
It is a small location, there is a meeting room, a fully equipped kitchen, a printer and of course wifi. During the day, an average of 5-10 people work there, it's mostly quiet and you have 24/7 access to the office.
I am very satisfied and can recommend the space. It is especially suitable for people who live in the local neighborhood. If you expect a large community or an extensive event program, as is often the case in other coworking spaces, you should rather look for something else.
