I'm always suspicious of first photos that show something other than the front of the house. Where is the front door?
The listing and the floor plan don't make it clear that it is a five bed house with a one bedroom apartment attached
I don't care about the pipe museum or the town's history other than as a footnote - I don't want to have to wade through all that blurb to get to the details on the property
Kitchen is nice but small for the size of house
Move the school photo from the lounge shot
Get a proper bedside table for the room in photo 6 and take the towels off the end of the beds (you're not selling a hotel room)
What is the room in photo 7? Move a bed there, if only for the photos, to make it clear what it is and what size bed will fit in there. Ditto for photo 10
Photo 8 would really really put me off. The bathroom looks to have been done up recently (so there will be a premium attached to the price) but the copper pipe all along the wall is ugly, and I don't want to have to use an electrical heater for hot water to wash my hands.
What's the random rectangular pipe in photo 9? (And clear away the cable on the floor for a new photo!)
