No commuting which means time can be spent on reading up materials, doing actual work, or going to the gym.
Meals is also an important matter. Working remotely, I feel I have more control on what I eat. Typically i tend to pick up food at a cafe/restaurant, which depending on my pick diminishes my productivity. Working at home means having access to full fledge kitchen like stove, oven; I could do weekly/daily groceries to prepare healthy food like salad, yoghurt, etc.
There are still some setbacks though when it comes to communicating and working in a team. We tried to solve that with Slack and project management tools (ie. Basecamp, Asana); it works for most projects, while some I supposed we are still looking for the right way to get everyone on the same page mainly because there are a few stakeholders involved.
