I never used to mind working from the office when I had a private space (cubicle) where I could retreat to when the task commanded deep focus. Somewhere around 2010 however the dreadful 'open office' took over and I found myself at a long table in the middle of an open room with little separation between other employees. This is an absolute nightmare and productivity killer for me. I was glad to read the opposite end of the spectrum in many of these comments and it is now even more apparent to me that great flexibility for the individual is needed to maximize their own style/situation/productivity.
