Our last apartment had a pretty large dishwasher and sink, so we could go up to 2 days without doing the dishes - even with two kids and eating at home for all three meals!
Our current apartment has a tiny dishwasher and sink (they're actually stacked on top of each other, but I've never seen before), and we can barely go 1/2 of a day without doing them. It has a big impact on quality of life, since it feels like we're doing dishes all day and night.
How many days of dishes can your sink and dishwasher hold?
