Have You an Apartment?

A friend of mine is looking to move to the Bay Area and could use a little help finding an apartment. If you happen to know of something that fits the following criteria, let me know and I'll pass it on.

* move-in date in October
* studios, 1-bedrooms, MIL-apartments, cottages, sublets, maybe renting part of a house or sharing a house depending on the people
* no or few steps/stairs (1 flight of stairs at the most)
* close to central urban areas
* sunny, even in winter
