I don't know the area.
What I would say FWIW for your friend , some people , unless they simply cannot afford what they need any other way , won't buy a house on a busy main road or with a bus stop nearby. Now your friend did , so there will be others , but that is a compromise she needs to be aware of. The kerb appeal I would say is neutral - very tidy but not a house which would grab you - esp with your back to the main road.
inside I think the house is lovely. I would just say that for all that downstairs space having a kitchen / dining table which can seat 2 adults and 2 children is fine day to day but there isn't much dining space compared to having two relatively large seating areas ( in the kitchen and the sitting room) Bedroom 3 is small but fine for a baby / young child.
I would say that nothing about that house , for a person who likes the area and the specific location (ie on the main road ) isn't fixable and people who can't see past wallpaper etc well .....
So I would ask the EA for better feedback than "not for us" but people don't always want to say so that may or may not work. I would look at houses which were put on the market at the same time for the same price and see which ones are selling - that may give a clue.
That said in the current climate 2 - 3 weeks is almost nothing and she is getting viewers. I think it's a hard market at the moment. I do agree , I am ( not Scottish market) put off by offers over. What do they realistically think they might get and may be just put It on at a price near to that.
Anyway I can see lots about it to like so I wish her the very very best.
