Carolina's description of her place was accurate. We enjoyed our stay at her AirBnB. The Pasadena area has really great restaurants and the plave has a nice vibe, especially "Old Pasadena".
Access to public transport was fantastic. We used the buses to get to both Universal Studios and Griffith Obsevatory. The Metro Gold Line "L" is in walking distance and was a +-25min trip to Union Station. The only long trip was from Pasadena to Santa Monica ... but was worth the trrip.
We used the RED Metro Line several times ... but each time we felt that these trains need a really good clean !
Enjoy LA !
