I like having a separate work space, a separate work computer, and half an hour's bike ride between work and home. But you can still do those things while working from home, and you end up living cheaper with a more customizable workplace (I can play whatever radio I want, I can set the temperature how I like it...), and no-one looking over your shoulder (I really can't understand seeing that as a positive). If you try to just work in the space where you were living without adapting it at all then yeah it's not gonna go well. But there can be upsides once you've taken the time and effort to adapt.
