@Damion10,
The primary recommendation that I have for advertising during slow periods is to also post on other platforms, such as Booking and Expedia. We've found that the popularity of platforms is geographical. For example, Airbnb is very popular with North Americans. Booking is more popular with guest from continental Europe, and Caribbean and Latin America. Folks from the UK will often use Expedia, especially if you opt-in allowing your property to be a part of a package. This also gives you a backup if/when you have a SNAFU with Airbnb.
You have a very nice place, and great reviews. You may want to update the tag on a couple of pictures and possibly the total number of guests. One is of two twin beds, and the listing says they are double beds (in the US twin = 39" x 75", double/full = 54" x 75", queen = 60" x 80"). Based upon what's listed, there are enough beds for 10 full-size people. The other picture is the one that says coffee mess which may confuse some folks. Mess is a term that is often used by the military, and means gathering place for socialization and meals, but the general population may interpret it as meaning untidy or something that's been left behind. I recommend changing the tag to something like hot beverage and snack station since you're providing more than coffee.
