Need housing north of Palo Alto (or in San Fran)

Hi there,
I am a graduate student at Stanford. My boyfriend is a young professional with a small dog. He has accepted a job in San Francisco and will be moving across the country in 2 weeks. He is looking for housing that is either in the city, or somewhere between Palo Alto and the city. I will be living in my own place down near Palo Alto--this search is just for my guy and his small but energetic dog. He is mature, friendly, respectful and responsible.

He is open to considering a number of options, including:

1. furnished temporary housing (either one room in a house or a small apartment if it is at low cost)
2. moving in with a roommate looking for someone to fill a room (he is a very friendly guy and you will love him just as much as I do--you must allow his dog to come along, though)!
3. an efficiency/junior studio/studio/one bedroom apartment/cottage that is affordable--around 1400 but he can be flexible on that price depending on location and other factors.

If you think you have something that he would be interested in, just shoot me an email. I'll pass the word along.

Thanks!
