We have new neighbours, moved in two weeks ago. I put a card through the door to welcome them and put my number in it to introduce ourselves. The woman texted to say thank you for the card which was lovely. We never heard our old neighbours (we're semi detached with the halls and stairs adjoining) however we now hear the new neighbours going up and down the stairs very loudly, they must be pretty heavy footed. They also have two young children who I think run up and down them fairly often. They seem a lovely family :) just wondering would you mention it or just leave it and put up with it? It really is loud and can be heard over us having the TV on in the evening. Just so odd to me we never heard our old neighbours at all through the wall and they were a young family too...
