i am going through something similar, though not quite so extreme. i am moving out of a shared house that i had been in for 3 years into a 485 sq ft studio. there is nothing like downsizing to make you think about what you own and what is important.
i would just build in a breakfast bar, and use stackable stools to save space. i also prefer doing laundry in-home than using the apartment's laundry. instead of getting a wash/dryer combo, i have been considering one of these portable washing machines: http://www.laundry-alternative.com/products/Wonderwash.html
they are much cheaper, faster, and practical for a single person or a couple. i would just designate two laundry days/week to do it, then line dry. they have spin dryers on the same website, which will take out most of the water for a quicker line or machine dry.
good luck! this is a fantastic way to save the environment, and $$ too!
