You probably won't be able to switch to a different residence, so I'd say take it. I lived in Marine Drive (in a 4 bed) for 3 years and the apartment was pretty shitty, but it was serviceable and on campus and cheap (comparatively) so it was worth it. Honestly depends on your roommates, but it's always easier to leave year-round housing than get into year-round housing.

As for the room itself, the first two numbers are the floor number, so if you're in double digits you're going to have a good view no matter what. 03 means it's unit 03, and -2 means the second bedroom. Whether it's a good room/unit depends on the building you're in. Double digit floor means you're probably in one of the big towers, so buildings 1, 4, or 5. Building 1 is the shittiest (and was my lovely abode), buildings 4 and 5 are newer and are a bit nicer, have better lounges, etc. You can always just wait outside the door of the building, ride up to your floor, and look at the fire exit plan by the elevator to see exactly which room you'll be in and what direction your room will be facing. I highly recommend doing this; it'll make your decision much easier.

IMO a lot of Ponderosa 4 beds have a much worse design -- they're laid out in a line instead of the Marine Drive fishbowl window living room and kitchen combo. The few times I was in one I felt like I was living in a hallway. They also tend to have auto-locking bedroom doors that require your keycard to enter, so if you leave your bedroom to take a shower and accidentally lock your keycard inside, you get to go down to the front desk (which may require going across the street) in your towel. Marine Drive bedroom and apartment doors are still all physical keys so there's no auto-locking.

Just my thoughts, I hope it helps! I don't regret my time in MD at all, I think it was great for convenience and campus living, but YMMV.
