katy trail... I'm told I'm a good hostess fairly often and I always seem to have people staying with me, so I'll share some things I think are important. You've already gotten some great advice, but here are a couple more little tips:
Make sure the guest bathroom has both tissues AND a wee trash can! I don't know how many times I've stayed at a friend's/relative's home and had one, the other or sometimes neither, but not both! Crazy, huh?
I always let guests know how I roll soon after they arrive. For example, I make sure to tell them to make themselves at home, poke through the fridge for whatever they like (I'm fine with that) and that I'll be preparing breakfast and/or dinner, but they should scrounge if they get peckish or want lunch while I'm busy doing something else. I leave teabags in a handy container out on the kitchen counter. And I think it's good to give them a quick overview of how to use the microwave, the tea kettle, where the glasses/cups/plates/silverware are, etc. That lets them understand you're seriously ok with them poking around -- if you are, that is!!
Sometimes I'll print up a little menu for the breakfast they can expect to enjoy and leave it on their pillows... sets the tone for the visit that they will be pampered and I consider them special. And I agree that fresh flowers are always a welcome touch.
Ask often if they are comfortable, make sure there are throws around they can wrap up in... older folks are often colder than we think. Make sure there is access to extra bedding for them at night in case they get cold. And extra pillows are appreciated as well.
As for chatting too much, well, they may be eager to hear every word you have to say! But just pay attention... you'll know if you're talking too much.

And if so, it's easy to just ask a question and let them waffle on for awhile. They'll appreciate that, too!
Have fun -- that's the most important thing!!
