I work from home most days, go into the office one day every two weeks. Office is about 80km away and takes around 1.5h each way (at a cost of £42.50 in train fare!)
When we saw Covid was going to be a long term thing, we had our spare room at home remodelled into a proper home office, so now have two permanent desks with large monitors setup. My home office is actually much nicer to work in than going to the London office. I have better tech at home (faster internet, bigger screens), and it's quiet so I can concentrate. I'm more productive at home than going into the office.
