<human>: Could you distill the essence of the text into 1-3 sentences?

So, I'm planning a solo trip to San Francisco for **2 weeks** around the mid of March, and I'm trying to aim for **under 1000$** for flight, accommodations and insurance, and if possible to add food, gifts, personal purchases and entertainment to add up to under 1000$.

I've used AirBnB before, but San Francisco is much more expensive.

**What I'm asking are two things**:

1. Is it possible to enjoy San Francisco staying in the Oakland area?

2. Are hostels are a safe, reliable place to stay? I've never really stayed in one before and am quite used to the privacy of a room, albeit with giving up community feel.

Found a few good hostels, I like [The Green Tortoise] 

Does anyone on here have any experience with The Green Tortoise, or would there be any better hostels in the San Francisco area that might be cleaner/safer? I'm most concerned about dirty bathrooms and someone stealing my personal belongings (possibly bringing my laptop, I will be buying records and maybe clothing while in SF).
<bot>: Can I enjoy SF staying in Oakland, and/or are there any affordable, safe, clean hostels in the actual San Francisco area?
