Well done to the person that found the before pictures. I had a lovely time comparing them.
It's a bit too minimalist for me, it needs more period furniture, but on the whole I feel it's improved.
The carpets would be a problem for me though, I hate marking carpets. I'm not sure about the staircase, I think they should have at least left the handrail wood. I don't think that you can see enough to know if it worked.
The grey would also need to be repainted, cold northern weather and grey= depressing.
The neighbours...far too many, and they would all be looking in and from the terrace you would see into their gardens.
