The interest is there if you are getting viewings, so it's not the photos or the listing, unless they're misleading in some way so people are disappointed when they get there.
It says two generously sized double bedrooms but one definitely looks like a single bed (or pushing it maybe a 4' wide 'small double' bed?) in a very narrow room, maybe only 5 or 6 foot wide. That's really not a generous double room, or even a double room at all. What size is that bed and how wide is the room, because I bet that's it?
Also the way the photos are ordered it looks like there are two proper double beds, but it's the same room from different ends 😆
So what you are selling is a 2 bed with one double and one single room, but that's not what the description says...
Having a floor plan and room sizes in the listing will mean people can judge if it's the right size before they come out for a viewing.
