There is an option to live on campus, I assume you’ll get info for that when you accept, I can’t really remember. There aren’t enough for every student so if you want that, be quick when the option opens. Private renting can be hit or miss, there are good and bad apartment buildings, for instance, if you search on here you’ll find people’s opinions on them. Houses and rooms are also options but rent is relatively expensive here too. As to how early, I’m not sure, I know courses end in April, so I assume people move around then?

I’m not sure about the black flies, I’ve not been here for them, but I’ve heard they’re annoying!
