To bring another opinion to all the other comments, each week I'm trying to go into the office more often than I already do (2-3/5 times per week currently) which I feel is not much, but after reading some comments, you guys must think I'm a maniac already lol.
Now why would someone do that? First, I got a new job like half a year ago and I absolutely love it. First of all, my current commute time is around 25 minutes, door to door, in clean public transportation. Second, we got free water, Softdrinks, Coffee, Snacks, even fruits and cereal in the office. So no matter what I need to energize, it's there. At home, I usually don't. Or I do, but still, it's better to have 'free' you know?
Also, I love my colleagues. They're very young on average, incredibly skilled and highly intelligent. Also from many different countries. It's always fun talking to them and getting different insights on all kinds of things. We also usually take smaller breaks to play table tennis or table football.
Home office is great too, for days I really need to focus or have a lot of meetings. Or have private appointments, deliveries, or whatever. I can also take Homeoffice whenever I want and no one cares at all.
But still, it gets boring and lonely. Being in the office is great for my social factor and currently feels more like going to see friends, rather than working.
