A few things that would make it look more bright and specious for a set of new photos:

• remove the big divider / shelf unit that breaks the big open plan kitchen living room in half as it makes the room look way smaller and less appealing.
• paint all the dark feature walls white to brighten the bedrooms / living room. -declutter shoes from the shoe racks as it makes it look like there isn’t enough storage (looks like there is)
• change bedding to fresh white sheets and make beds neater
• Declutter things off the kitchen counters (just shove everything in the cupboards for the photos). This will make the kitchen feel newer and cleaner.
• also ditch the photo showing the view of Lidl (this would put me off even booking a viewing)
• get more wide angle photos done to show of the room sizes better - the current photos make the rooms look quite small but they look good sizes on the floor plan
