How quickly can you usually move in?

Move-in is possible at fairly short notice. You can often move into an office within just a few days, sometimes within a few weeks. The decisive factor is whether suitable office space is currently vacant and how quickly coordination with the coworking or flex office provider works. Compared to traditional office rentals, this is significantly faster and easier because the offices are designed to move in quickly from the outset.

Is the Flex Office model an alternative to the classic office?

Yes, this is now a very useful option for many companies. Coworking and flex offices offer significantly more flexibility, less organizational effort and generally shorter contract terms than traditional offices. This is often the more relaxed solution, especially for growing teams, hybrid work models with lots of home office or companies that want to start quickly without making a long-term commitment. In many cases, it is also worthwhile to compare the costs more closely. This often shows that flex offices can also be financially attractive.
