I read one double bed under sleeping arrangements, and this listing states it accommodates 4?
My advice is just re-read the listing as if you were a potential guest. Then you will be better able to see what is confusing in the listing (how many people it can hold, is it an entire place or a private room in a space where you will be staying as well), and make some adjustments.
Also, take a look at other listings in your area. It has helped me quite a lot to see how other people present their photos, descriptions, etc. You can get a good idea what guests might be looking for that way.
