Same here. As described in the schedule I posted elsewhere in this thread, I tend to come to office at 12:00 - 13:00[0]. And I like it quite much. Most of the cow-orkers in my room work ~09:00 - ~17:00, so there's 4-5 hours of overlap in the afternoon, followed by 3 hours of peace when I can focus and get something done. There are days when I do actually manage to come as early as 08:00, and those days I really miss being alone in the room.

[0] - Had long battles about that with my boss. He gave up after a year, realizing that there's no way to make me come before 10:00 regularly (my sleeping patterns are weird), but I am there when it matters and get the job done.
