Then when I asked about using the washer for our personal laundry, she acted all annoyed. 

Also I had to deal with something called the Self Sufficiency Test which was super annoying.

That's annoying. 

It is very annoying.

I just want to make sure that we nail the parts that are typically the most annoying or difficult for people.

Depending on the building, layout and system, sometimes those issues are hard to combat no mater what.Running toilets....annoying but cant force a fix...... often easy DIY fixSinks not draining...... pull the trap and clean them out...pretty easy to do yourself....if you are lucky, then that will fix you issue....if not its further downstream and you will need a plumber.Water intrusion......best you can do is frame the conversation around the fact that the issue is destroying his property and investment and it's going to cost him more $$ in the long run if he doesn't deal with it now....appeal to his desire to make $$ on this place.....Sucks but sometimes you have to just band aid the issue as best you can and/or fix them yourself until your lease is up and you move.

I am very concerned this is going to cause them to move into a living situation that is loud and quite annoying.

“ALL FLEAS CONVEY”I have run into fleas infestation a few times and it annoying and gross but part of the territory.

I would have to agree that this is very annoying. 

I'm sure some client's might get annoyed that it's not plastic but I love that idea lol
