What little things did they do that made it easier on you?
We've just started and the dust and noise is making everyone a bit grouchy...
we've tried he be as considerate as possible in that we've delayed the work significantly so as not to do it when people we're working at home / homeschooling (not easy as it's a house in need of a lot of work and we have 2 small people ourselves plus it will cost us a lot more now). We've been through all the proper processes re party wall and shared all designs etc before submitting for planning to make sure no one was adversely impacted... and we specifically briefed the architect to make sure noones light was impacted by the side return design...
It was always going to be a large project for whoever took it on... but I still feel bad for the disturbance (today is drilling out concrete floors) .. is there anything your neighbours did so you didn't hate them forever?! We plan to live here long term and would love to get on!
