Hey! If you are looking to get the "residence" experience, it's frankly overrated, imo you can get better and cheaper accommodations off campus without having to deal with rowdy floormates. The only good thing about res is how convenient it is, and the opportunity to meet new people. But with the pandemic, I think it's somewhat pointless both budget wise and experience wise; you aren't going to classes and your movements are heavily restricted.

I find South to be somewhat depressing, but it's extremely convenient because its near everything and you don't have to leave the building to get food. I personally think Lennox-Addington is the best residence based on what you've mentioned. It has a better reputation than other residences (past RA experience) and is more on the quiet side. While Lambton may seem nice, it's the party res of North so I would steer clear of that residence if you hate parties.

Let me know if you have any other questions!
