@Bryck0 A few thoughts:
1) To clean a place that size for what I assume is a cleaning fee of $30 (I see £ sterling) can't be possible. As such I assume you are effectively charging some of the cleaning in the nightly rate. This then makes a longer stay more expensive and subsidises short stays. I would up the nightly rate significantly and then give a discount for stays of 3,4,7 etc days. You could lower the rates and up the cleaning fee so it incentivises longer stays.
2) You could set a min stay of 2 days. We always set ours at 3 and accepted that we lost some business but, as we cleaned ourselves, it was just too much work otherwise.
3) I am not at all sure what I would get if I booked your place. Is there outside space? Do people expect to sit out where you are? Take a look at similar listings near you and see how others 'sell' their rentals.
4) Have you gone through the amenity list since you started? Once published the list gets way longer for you to choose from so its worth revisiting it.
Hope this helps
