Interesting watch. One might assume that living alone in such a manner could be quite lonely (wasn't there an entourage of men and women when he flew in last year?), but then again family members might find it harder to settle in Manchester, which in turn could be unsettling for the player. I suspect that top clubs, in general, are quite good at helping players settle and keep a keen eye on their physical well-being, but I suspect they are less active in monitoring their psychological state. That said, Laporte strikes me as someone who has been an outsider for most of his life, never fully French and never fully Basque, so perhaps he's had to adjust to living in the margins and that can only be done alone.
On a footballing point, it's interesting that he came from a defensive system which was intense, man-to-man, and where the focus was primarily on winning duels but also on passing accurately. I wonder if that background makes it easier to transition into English football and Guardiola's style of play.
