A SPACE Greenbelt
Speed test is shown for a user group, not for the whole space (the whole space has way more). The biggest space of indie cowork leaders, A SPACE. Entrance is opposite Greenbelt 5, above the Union Bank. They have 4 floors, and the 5th floor entrance is for the drop-in coworking Lounge - desks, sofas, balcony, art gallery... free liquids, easily the fastest internet of any cowork space or cafe, plus IT support and tons of connections . You can pop in and buy, or book in advance online - cheaper for more passes, monthly memberships available, free entry to most of the events, and they sometimes give a free trial. Easy.
