Owning your own home

having looked at lots of flats online recently i don’t see anything wrong there that would put me off having a viewing, maybe the shot of the balcony could be done from inside and a bit lower down so you obscure the busy junction and have more trees/church.
You have a lot of stuff but it’s not untidy, reducing the ‘things’ on display a bit might help? surprised you haven’t had any viewings yet.
can’t comment on the price, no idea of the area or what stuff goes for.

if you get no joy i would consider some new pictures on a brighter day and remove a few things.

i spent a whole day shooting my parters flat (i’m a photographer and have shift lenses for architecture/interiors) moving ‘props’ and giving some thought on what to focus on etc, i definitely think it helped sell it and go under offer in a week after 10 viewings.

This may just be me but I always like to see the total square footage on the floorplan. It wouldn't affect my decision to view though.

The first thing that jumps out is the photos that emphasise the big road outside. You definitely need an exterior shot (it's also dubious when they're skipped) but not one that makes it look like your flat is on a motorway junction.

Personally I don't think it looks that cluttered apart from the chair back in the third picture and the TV bit looking narrow (I know a lot of modern flats have that though).

If the total sqft is decent (I'd guess about 700) then I'd want it on the floorplan. Might just be me but total sqft was something I used a lot to judge places online.

But also I wouldn't stress about not getting instant viewings. It can take some time. Keep in touch with your agent, see what they're doing to get people through the door. They should have lists of people who are looking for similar stuff and pushing to get them in.
