Our house has a front room into the diner and the door to the kitchen blocked up (not done by us) but they put a serving hatch, at first I wasn't sure but actually it's really useful and solves the problem of the kitchen and dining room not being joined together. I'd rather have the wall space than a doorway. Could that be an option?
I wouldn't take everything to heart thats said on here. I put my old house on here before we moved and apparently I needed to re render the outside, have a new kitchen (it was new), a new bathroom, redecorate every room (they had all been done), move essential furniture, buy other furniture, basically I almost needed to knock the bloody thing down. There was nothing wrong with it and it sold to the first viewer within 10 minutes of him leaving. Some things were helpful like stuff on the walls etc that I didn't notice, but a lot of the advice just wasn't correct. Our house was a fixed price that was realistic and nothing we would have done to it would have increased it so it would have pointless to spend money on it.
Your furniture wouldn't put me off, it's stupid that people can't see past a vendors chair. The bathroom tiles would be slightly off putting because there are a lot of the pattern it a tad dated. It's a great size room though. The older photos where you can see around the corner of the kitchen and the longer bedroom from further up are much much better. It's surprising how extra photos and taken from different angles makes a difference. Your garden also looks bigger in the older photos. That long narrow bedroom doesn't look nearly as bad in the older photos, it looks perfectly fine.
I honestly think ll ypu need to do is brighten up/create a grown up space outside and rejig the furniture in the long narrow bedroom and get better photos taken. Potentially sort the tiles in the bathroom if you can and maybe make the walls a bit less bare with a picture or 2. I really don't like grey and it is everywhere but I would redecorate any house I buy so I certainly wouldn't redecorate for selling because it would be unusual for a buyer to not do it themselves anyway. It loos like a blank canvas so easy enough to change.
