As with any workspace, you have to find out the rules and regulations of each space. Some coworking space has fixed operating hours, while some are 24 hours. The noise level varies as well in each space. The setup and facility - might or might not work for you. Making phone calls in shared space might be discouraged but some will have provided meeting room space.
At The Network Hub, we provide 24hr access to all our members, we have meeting room and open lounge areas for people to take calls. We encourage all potential members to take a tour of the space to see our set up and facility in person, that's the best way to get a feel of the space and to know whether it is the coworking space for you.
