# Working from home ('free')
Working from home is great for about 6 months, then isolation kicks in and the divide between work and relaxing disappears. Given my situation (single, no kids) I quickly become very lonely. A separate in house office helps for a separation between work and not-work, as long as you have the discipline not to use your office space for something else. (locking your office after work hours helps).
# Renting an office (~1000 eur/month)
Can quickly become lonely as well, and can be quite expensive once you add costs for the cafeteria, internet, insurance etc. It does give you social interaction during lunch breaks, and no disturbance during work. There is also a very distinct separation of work and relax time. I did this for a couple of years, but once again I felt lonely and was craving for social interaction, a.k.a. colleagues.
# Coworking place (~300 eur/month)
This is my current setup, I rent a fixed desk in a large open space. In this space there are about ~8 fixed desks and about 10 flex spaces. We have sound insulated phone booths, so it's usually pretty quiet here. My 'coworkers' don't understand my work but that's ok. I use noise-canceling headphones when I need to concentrate. Personally I love it, it's been my favorite setup so far.
