Best Neighborhoods for San Francisco SA

Incoming IB intern in SF FiDi this summer. My roommate and I are debating where to live and stuck between a few different neighborhoods. We're currently set on either Nob Hill, Russian Hill, or the Marina District. Nob Hill and Russian Hill are closer to the office and likely more walkable. However, my roommate and I both have Ubers to and from the office comped so I'm not sure how much this should matter to us. The alternative is to live in the Marina District, which seemingly has more things to do and would be about a 15 minute Uber but is obviously not as walkable to the office. Most of the Russian Hill/Nob Hill places are about 20 minute walks at a minimum too. I'm unsure if Marina has anything to offer that Polk Street doesn't in terms of entertainment to justify the greater distance so would appreciate some advice here. Also, any advice on deciding between Russian Hill and Nob Hill, if that is the direction we should move in, would help us greatly.
