First, you need to know is the co working space location. Is it near to where you live? Can it be easily accessed by public transportation? Checking out the location of co working spaces that you have in mind should be considered as it will also affect the time you will spent in going there. No need to rely on your old wood watch or your alarm clock so you can brave the traffic. Remember, you should not waste your time being stuck in the midst of traffic.
By simply securing a desk space for you to work may not be enough. For other creative and likeminded individuals, they value the essence of being around people who share the same interest. See if the community of freelancers and entrepreneurs in the co working space you are working into is at par with you. Whether they love doing workshops or just conducting seminars on How-Tos. This shall enhance and encourage participation projects close to your heart.
