Aloneness means detachment as one performs ones worldly duties and goes through the motions of living. Detachment from worldly affairs takes us into the realm of God. Solitude feels good and is necessary because the peace of God gives contentment to the mind. The simpler the living the less noise one is allowing into ones life so that the better the focus on the serenity of mind that comes from realisation of the existence and nature of God. That is the bliss of solitude.
