@Paige219 It's a nice space, but I also find it far too monochrome. You need an accent color to liven it up and the bit of blue doesn't do that. Maybe salmon, or a warm golden yellow? Gather up some things you have around that you like the colors of- a plate, a pillow, a book, whatever, and bring it into the apartment and walk around with it to see what looks best with what you've got there already. I find that it's easier to get an idea of what a color would look like if you use an actual object rather than little color swatches or your imagination.
I would also can the air mattress offering. Once you start giving guests the idea they can cram more people in than your max guest count of 4, they will cram even more in. I also find it a bit strange that you put 2 queen beds in one bedroom- who do you see as your target market? It certainly wouldn't be suitable for 2 couples, as they would have no privacy. And if it's a group of 4 singles, they probably wouldn't be into sharing a bed. I would have put a king size bed in there and listed for 2.
You mentioned here you were thinking of kids when adding the airbed, but your listing looks more like an adult sort of space, not a family-oriented space.
Guests tend not to read lengthy descriptions all in one paragraph. You should pare down "The Space" section to about half or less of how it reads now. I got cross-eyed before I was a third of the way through. It's far too wordy. The Space only needs to describe the layout of the place, the rooms, etc. (and it's good you mentioned no elevator) but there's no need to put extraneous info in there about laundry pods and that sort of thing.
