You are right to be skeptical 2 adults don't require 2 bedrooms for 2 months.
First, I usually try and scare them off just asking simple things Can I have the legal names of both guests please. Just like to document who is in the property.
Please confirm you are comfortable with no pets or guests at the property?
Use the fact that your new to your advantage. lol Since I am new so we both are jumping in, I would feel more comfortable doing maybe 15 days and if we are both in agreement extending your reservation can be done another 15 days.
I confirm what I have disclosed in my ad and any rules that are particularly important to me.
When they see their 63 days doesn't distract me from my business management. They usually go looking for an easier target
