We've rented a number of places, so my kitchen snags are well-tested!
Irritants:
If there are child level cupboards, if they are all hinged on the same side, meaning (a) the space inside is all cut up and (b) there's no chance of slipping a child lock through the handles, which is the easiest way to child-proof.
Blanco stainless steel sinks always seem to have stupid half-sinks with strainers or bin-holes with the hole capped, configured in such a way as to be incredibly unhygienic. I hate them. When we have our own house I want a double sink or single sink. I also hate those stainless steel drain strainers which also double as a plug: I think they're unhygienic, too!
Kick-boards are never flush: also unhygienic!
You need a splash-back for the range top. T'would be good by the bin, too.
Space for kitchen bins is important. Not just for a bijou bin, but a big one, and also for the recycling! This should be close to the door through which you take the rubbish out!
Breakfast bars are un-ergonomic for adults and dangerous for children (not just for sitting on, but also for bumping their heads into). I wish they weren't so bloody fashionable!
Built-in appliances (by which I mean co-ordinating cupboard doors over fridge, etc.) are a high-maintenance, showy, empty con.
Cupboards which don't go to the ceiling get filthy.
Range top needs plenty f space around it, on both sides, for spices/sauces/spoons/dishes while cooking!
If the working triangle is impossible, that is not just an irritant!
Hope this all helps!
