We're quiet, nonsmoking couple in our late 40s. Love to see pets around, especially cats, despite hubby being allergic. He doesn't like dogs though.
We love a comfy, firm bed, preferably king - I always look for that in the descriptions, and will pass up any that have a double bed. Or heaven forbid, a waterbed, I just saw one today, yikes!
We prefer airbnb over hotels any day, it's a great way to get even a little bit of a feel for a place we travel.
