This is completely offtopic but as I was looking into the coworking universe in Berlin I thought I simply share my research with you. Subletting, shared office spaces and short time renting have been around ever since people were working together in offices but the whole thing got a whole new dynamic with the rise of the label “coworking”. With ~100 different spaces and options being available by the end of 2019 Berlin also seems to be the capital of coworking in Germany.
There are actually some very helpful websites out there giving you a better grip on what’s available in terms of coworking possibilities in your city. Whether you’re looking for short-term solutions such as day and week passes or long-time setups on a monthly basis. Additionally you can choose between flexible or fixed desks or even your own reserved office space within the coworking facility. On top of that there are plenty of further options to chose from ranging from the basic wifi connection to printers, scanners, projectors, meeting rooms, kitchen, catering, accessibility, dog-friendlyness and community events. Last but not least location and transportation are crucial points to look at as well. Depending on your choices on all of the parameters prices vary quite a bit somewhere around €20 per day or a few hundred Euros per month.
As a starting point you may want to take a look at these great aggregator websites that might help you to drill down the available spaces according to your preferences:
As the overview is quite extensive and tends to be a bit confusing I strongly recommend having a look at these articles that condensed the available spaces into carefully selected subsets here, here and here.
