Despite all their shortcomings (and I have ranted about them on here a lot in the past), the seem to have close to a 100% occupancy in Berlin. It does often look like they are less occupied though (partial empty offices) because the claim of "you can easily move to a bigger office" isn't true and companies rent offices that are bigger than they need them to be.

But what occupancy % is needed to do well? Considering you could easily pay rent with a 50% time occupancy AirBnB, maybe it's similar to WeWork.
