Not ideal to have a plumber turn up at 8:30 in the morning and start a very loud pump outside our window for the unit downstairs. It even caused the house to vibrate and this went on for about an hour. Why wouldn't that be organised for a time when guests aren't on-site? Pretty unprofessional in our opinion. Also dishwashing liquid was practically empty and there wasn't an actual brush at all. These cost like $3?
