I stayed at Kirsten's home for a couple of days whilst visiting the city, and had a great stay - it was quiet, clean and comfortable. Kirsten herself was a wonderful host - friendly, welcoming, and knowledable about the local area.
The area seemed quiet and safe, and is an easy drive from most of the sights I wanted to see in LA (I had a rental car, and had no problems parking right next to the house).
All in all I can definitely recommend Kirsten's home as a place to stay if you're a solo traveller visiting LA, and would definitely return. Many thanks!
