@Paul41 You have a really beautiful home with some excellent design touches. It looks like a great place for large groups to stay, if and when your local laws allow for masses of people from mixed households to share a property (I'm writing from a place that's a long way off from that). But if you've organized your sleeping arrangements around the kind of business that you get from hen parties, I don't know if you really have much hope for a vibrant midweek trade.
I could be wrong, though - as an expert in the Liverpool travel market, what occurrences would normally draw large groups of people into your city in the middle of the week? These would appear to be your only real opportunity given the current layout. Bear in mind, despite the fact that your home is very tastefully appointed, the overwhelming majority of travelers with a budget over Youth Hostel level do not want to sleep in multi-bed dormitories when options with more privacy are available. I can't help but look at your very beautiful accommodation and think how much more valuable it would be as a house with 5 private rooms and a 10-guest maximum rather than a makeshift hostel optimized for the kind of parties that will ultimately cost you a lot in damage.
