Hey, I wanted to share with you this YouTube channel that I just found (in case you didn’t know it yet). The owner has made videos with the ambient sounds of each house’s common room. This is the Slytherin one (which I find very relaxing and it helps me to concentrate when I’m studying).
You can find too the Hogwarts library, the Burrow and other Harry Potter’s scenarios - and it really makes you feel like if you were there.
Hope you find it useful :)
