I mostly love working in a coworking space, the one I'm in is something around 150-200 people.
I work in a small company (6 in the office, and 2 remote/roaming), and I think that working in a coworking space gives me the best parts of a larger company, and the best parts of a small company.
There are lots of social events and opportunities to hang out with other people in the space, we have different events and presentations on all the time. I also get all the nice parts of a smaller company, like knowing all my coworkers and the CEO personally, and a lack of office politics and a chain of command, I don't quite report directly to the CEO, but I am in regular direct contact with him.
Not everyone here is tech either, there's quite a few small non-tech startups and small businesses, which is great to get that contrast.
There are some disadvantages though. Some people are inconsiderate or ignorant of the fact that it is an open office and that you're sitting next to other people, and they have extend conversations, or phone calls (which are the worst, some people practically shout into their phone). We have dedicated noise dampened phone booths that work great, as well as meeting rooms and meeting booths for people that need to be loud, as well as a corner of the space that's for people that need to be noisy.
By and large the majority of people are fine though. Hot desking isn't too bad either, since most people are there every day, so everyone has a seat they usually sit in. I'm pretty minimalist too, so all I need is some paper and my laptop, I don't need external keyboards, mice, or monitors.
It's a great community, it sounds really cliche, but it's more than just a place to work at. It's a great community.
