I lived here from 2006-2008 and it doesn't sound like it has changed. My friend's cars were towed. My car was towed from my parking spot, etc.
Biggest issue: My roommate and I were attacked in my apartment by a sex offender who wandered into the complex and was profiling us. SAN MARIN DID NOTHING. The management was interviewed by the police and they were sent the report. They blamed us and said our door must have been unlocked (It was not). Luckily our lease ended the following week but we got the hell out ASAP. To add insult to injury, they charged us $200 over our initial security deposit.
