All of this affects you less if you are in a shared flat compared to renting it alone. The flat can be vastly more expensive as you are pooling the money and flexibility is higher as you have less furniture per person and tend to be able to join/leave shared flats on less rigid schedules. (You can find many in the middle of the month, depending on the holidays etc.)

I lived in a shared flat in Germany which got a rent increase and other than all the young families in the building we really barely noticed it.
