It is a nice building in a nice area.
I have a 40min walk to it or 10min bus ride.
I like my colleagues. Sometimes you need to meet and solve problems face to face, and not have it be planned.
I like dressing up a bit, not a full suit but nice pleated pants and OCBD/sweater/blazer.
I have a shift schedule, sometimes I am the only one in the office, that is bliss :)
But my work is 100% in office. But not being shut at home is nice.
