Making the post to hopefully save someone time. I am not affiliated, have been asked, or received money for this review.
I was in Madrid for one week and wanted to find a coworking space to work from. I also needed it to be open 24 hours, since I am working with a remote team, on the opposite side of the world.
I called many places: WeWork, Spaces, and others. They were either too expensive, opened only during the day, or required monthly plans. The solution is: https://goo.gl/maps/i8jQY2EFT4AztWYo7
The check all boxes: affordable, opened 24h and paid weekly.
Address: Glorieta de Cuatro Caminos, 6, 6ª, 28020 Madrid, Spain
