The guy moved in a year ago and is a lawyer. He knew the flat above was let and can be according to the lease. The tenants are excellent but recently he has complained that the washing machine is on too much. I live on the top so he needs to take it up with the owner of the middle flat not me.
Surely you could have an issue with a washing machine whether rented or owner occupied? Why did he buy it ? he could afford a detached house if he wants privacy
