A Great Bed
Provide the best bed you can instead of moving old mattresses into the room. Strive to offer a luxury hotel experience when considering options for the guest room.
Invest in high quality linens for guests and always have an extra of sheets and bath linens. Since they are used infrequently, they should be well worth the investment.
A Place For Luggage
Make room for a luggage rack, or designate a bench or small table to rest a suitcase. Try to avoid your guest having to live out of a suitcase on the floor as much as possible. Make sure chest or dresser drawers are clean and leave a few hangers in the closet, as well.
Include at least one other option than sitting on the bed. A simple chair or bench would work nicely.
Resist the urge to place trinkets, knick-knacks or other such things in the room. Keep accents simple and visually appealing. The room should not reflect your style but again create the luxury hotel experience.
Make sure guests can control a light source near the bed to avoid someone having to stumble
around in the dark searching for a switch. Even placing a simple lamp will do the trick and can also provide a good reading light. Offer a fixture or lamp near the chair and possibly a table. A discreet night light is an option to consider. A lighted magnifying make-up mirror can add a much appreciated touch of lavish indulgence to the room.
Set up a television in the room and a DVD player with a stack of your favorite movies. Some type of music player or dock station would be a pleasant addition. Ensure any remotes have working batteries and place them beside the bed.
A lighted clock by the bed is a nice touch, but a better option would be a alarm clock with a music source (even just a radio). A notepad, pens, pencils and tissues, hair dryer and possible a spare iron would be helpful amenities to the room.
