TL;DR is WeWork just an open office but for (way too many imho) many companies/people in one space? Are Wework spaces similar across the world? I have to work in a central London one sometimes and I find it horrendous; it is almost literally good for nothing; way too noisy and loose for meetings (even in the closed spaces; they are glass and not soundproof) or actual concentrated work (with noise cancelling headphones it is bearable). At lunch, because most of the space is open and attaches to the central area, it smells like as mix of whatever people are eating which can be interesting (kebab onion with garlic sauce mixed with pizza mixed with fish mixed a spicy curry smell) and lingers for a long time. Nice looking wooden floors so when people wear heals you can hear them literally everywhere when they walk around (programmers who are supposed to be focused with noise cancelling headphones all look up every single time; noise, all glass, heals (probably female) so they look). Beer opens at 4 pm so drinking commences at that time too. Too many people allowed in there so if you didn't strictly book rooms they are all full and meetings cannot ever go over time. It is more a clubhouse than an office. I could not really work there for long stretches so I wonder if all these places are the same as a formula or this one is just unique that way.
