@Molly391 Yes, I saw there wasn't much space to put another table. The table isn't as important as the lamp, IMO, and you have that covered. Guests just like to have a place to put all the things humans normally have on their bedside table- their book, their glasses, their phone, but a couple could work that out.
Yes, the info about on-site host who lives upstairs is fine to put in the Other things to Note section.
Some hosts who have larger places that house more than 2 guests will put it in the Description intro, to ward off partiers, or those who try to sneak in more people or pets, who tend not to book places where they know their activities will be obvious.
