Agreed with Hufflepuff! Slytherin is probably my least favourite common room look, but only because I can't imagine myself living underwater for so many hours of the day - need natural sunlight. Also wouldn't want to wake up with a Grindylow looking at me in the morning from my window.
I'm like you. I love the Hufflepuff room the best because of all the plants and cute hobitty round doors plus near the kitchen! I love eating!😆 But in reality I'm a Ravenclaw!
