This fic is definitely excellent and worth a good night's read. At various times funny, moving, and sad, it does a good job of capturing the characters of Rowling's world.
However, there are a few small issues I have with it, primarily dealing with homogeneity. Every single character (with the sole exception of the asexual Rita Skeeter) is depicted as being straight, and all of them except the villains aspire to get married and have children. It gets a bit predictable and boring after a while. Also, around two-thirds of the way in, it starts to feel like the author was running out of steam a bit; the chapters start to feel very samey. It does pick up again towards the end, though.
If none of that fazes you, then you'll enjoy the fic a lot.
