Pothos!
And spider plant, for smaller plants. Schefflera & Monstera if you want something larger; I also have a ficus benjamina that is a real survivor in a well-lit, drafty home. It has not lived up to it's reputation as persnickety.

All seem to be pretty tolerant of neglect (example: I used to travel for work... a lot... in the winter... and leave the heat *really* low... and not instruct my cat-sitter to water).
The plants I've mentioned are all at least 10 yrs old, except for the schefflera, which is 5+

If you want something easy to grow, tolerates neglect, medium-low light, low water get a ZZ plant Zamioculcas zamiifolia. Ignore it, water once a month if in the right soil.
For something similar conditions only bright light and sun get a Jade. Again, tolerates neglect, water it once a month. Actually most succulents or cacti don't need much care or water and some will flower for you.

wow thanks a lot for great suggestions and so many good options :)
