Hi, I am from LA and hope you enjoy it. Universal is good, only problem with Universal is via Priceline you have to choose the general vicinity and you cannot guarantee you will be within walking distance of the metro and you might be very much stuck. Without a car Universal is definitely NOT walkable and worse it's on a mountaintop. Hollywood and Downtown are more walkable, and (where the hotels are) are safe by day, by night not really UNsafe, but quite seedy!!! I think you would get a very bad impression of the city which would be a shame... The metro is clean and safe, but riding the buses is - again - not UNsafe, but can be seedy. There's no nice way to put it but the bus it pretty much for the poor and recent immigrants in LA, everyone else has a car. And the areas you go through on the bus are pretty rough which might give you a scare... So there is a tradeoff... If you can find a good rate at a place that is AT Universal City itself, that would be your best bet.
