Guest Accommodation: Location, Location, Location

Don't place the bed lengthwise against the wall. This will require couples to have to climb over each other to get in and out of bed. That wouldn't be a very convenient or comfortable stay. I like the idea of surrounding a bed with two nightstands. On it, place an alarm clock and night light. So your guests can see what time it is and see where they're going. A night light can also be used for some light nighttime reading.
