is the med school in the middle of los angeles? Could someone tell me about the area? I tried researching it but didnt find any good info.
The post before mine is dead on - I'll just add a little.
UCLA and the medical school are in Westwood, which is in West LA - one of the most highly-desirable places to live in the LA area. UCLA is nestled right up against the Santa Monica Mountains, which divide the LA Basin and the San Fernando Valley ("The Valley"). It's bordered by the Culver City area, Century City, Beverly Hills, Bel Air, and Brentwood - among the best, safest neighborhoods in LA. The med school is in the old UCLA Medical Center, which lies just south of the traditional undergraduate campus. Walking from the med school area to the facilities on campus takes no more than 10 minutes.
The Westside is generally very heavy in terms of traffic, especially just south of the UCLA campus, where Wilshire and Santa Monica Blvds meet the 405. That can be a pain. But, being next to a freeway is helpful if you need to get around LA. The Westside's proximity to the beach keeps it cooler than further inland (e.g., Silverlake, Downtown) and it's pretty green and clean.
Westwood Village has pretty much everything you'd need as a student (grocery stores, Kinkos, cafes, restaurants, etc). I didn't spend all of my time in Westwood but it was convenient if I just needed to run to the store. It's generally safe though there are some homeless. Not a lot of nightlife.
Generally, UCLA is in a far better location than USC. You're 15-20 minutes (with traffic) from the beaches at Santa Monica and Venice, about 30-45 minutes (with traffic) from Malibu. Toward the East, you're about 40 minutes from Downtown and around the same amount of time from the amazingly awful Hollywood area. The Westwood area rent is pretty expensive but I paid more to live closer so I could walk to campus versus paying for a parking permit or dealing with the bus.
All in all, UCLA Med is in a great part of LA.
