going to Montreal-gimme your recs

Hello all, this is my first post in the Travel blog. I'm heading to Montreal in about a month and have yet to secure hotel accommodations. I may need to find something good/inexpensive on Airbnb. I'm looking for a hotel or room that is under $65. If anyone has good leads on that I would appreciate it. And while we are on this subject, which neighborhoods are best to stay in? Or if you just want to tell me about all the awesome places to visit while there that would be great too.

Also, the French I learned in high school has not aged well. If I make an effort to converse in French before resorting to English, will the locals appreciate the effort? Or should I speak in English without first attempting French? I don't want to come across as rude. Thanks in advance.
