Hogwarts Will Always Welcome You Home

The boys' dormitory in Gryffindor Tower was the first place that Harry has ever felt at home at and coming back to his four-poster bed each year is the epitome of "Hogwarts will always welcome you home". This scene is from Part III, where Crookshanks was the only one knowing what was going on and tried to hunt Scabbers down since September 1st. 

To me, Gryffindor Tower has always had that cozy, warm feeling of your favorite sweater on a cold day and it's always had that romantic air of English boarding school about it. Because who wouldn't want a massive four-poster bed, a snowy owl as a pet, and year after year of adventures?
