The bloke who owns the house next door (but lives abroad most of the time) has rented it out to his nephew who is a professional classical pianist. He’s getting his basement converted at his house in Battersea, so is slumming it in South Wimbledon until the work is done.
Been there 9 months and practices all the time. Initially quite pleasant, but quickly became REALLY annoying.
Was meant to be out at the end of last month, but he’s still there.
