I worked at one in Edinburgh for a while. 1) It was difficult to balance productive and social. As soon as the room hit a critical number and no one was talking, all assumed that this was the status quo and that talking was inappropriate. They almost needed a quiet area and a social area to clearly separate the two. 2) Proximity to more established startups (lived in upstair offices), who were happy to chat through technologies on the off chance meetings.
