I'm a year behind to these posts, but hopefully I can get some help here rather than starting a new topic. I have been accepted to a grad program at Brandeis, but I've never been to Boston so I'm a bit confused about the neighborhoods and such. I won't have a car and will rely on public transportation. I understand that Waltham is nice, but nearly impossible without a car. I've read instead to live in Cambridge, specifically Porter Square or Somerville. Is commuting via public transportation to and from Brandeis to Porter Square/Somerville possible? I know there is a commuter rail, but I want to know if it is actually worth it or considered more of a hassle? Any help, tips or comments about this would be great!! thanks!
