Need a good budget hotel in San Diego

I have traveled to San Diego many times from my home town Phoenix but usually I used to return by night. This time I would have to stay there for a week to attend a seminar. Can anybody suggest me some good budget hotels in San Diego?

San Diego has good budget hotels and what one ideally needs is a place in a good easily accessible location. I stayed last summer at a rather nice affordable place which is centrally located. Visit their site and check whether rooms are available or not. Good luck for your seminar.
