Good is that you face more serendipity than when working from home. But really, it is not that much more. After only few weeks, the novelty wore off and I got bored and saw more the downsides. Like super small tables, no dual monitor setup, always too cold, the commute, less free fruit, and the people. Some are quite nice and you realize that you need random social encounters but there are also the typical odd people to whom you cannot relate at all (like everywhere). Those people don't hurt but I remember one who reserved the best flexdesk the night before by leaving tons of her post-its and other papers there. No big deal but nobody who makes you happy either.
I knew most people I met there before. Bonding with new people without having a common mission was not easy, it just didn't feel natural (and I am rather the extrovert sales type of guy). So, you can still feel 'alone' in a coworking space.
I think a coworking space makes more sense if you need a space as a team and want or need to see each other f2f on a regular base.
For business meetings or doing interviews, I prefer lobbies of top hotels, they are even more representative than the best coworking spaces and at the end of the month also cheaper with full service included and no extra fee when booking some meeting room. And for two hours working away from home, I am a fan of Starbucks or any coffee ahop with good wifi.
