Helen is an extraordinary host - you can't wish for anything better. She was very responsive and communicative from the moment the reservation went through until the end of my stay. She was also very flexible an understanding with my arrival/departure times. We had fun and interesting conversations and she gave me a lot of great recommendations for places to visit in LA, where to park, etc.
The house is also great. It is very well located in a quiet area but close to all Hollywood points of interest. You can see a bit of the Hollywood sign :) Other than that the house was clean and had everything I needed.
I would stay back again at her house without a doubt. And I hope I do.
