Firstly, let me say that Billie (and Chris, whom we did not meet) was very nice and kind with us. She waited for us at the right time, and during the check-in she showed to us every corner of her house. It really made us more comfortable. Moreover, daily they left a pair of bottles of water for us (and, at the middle of our staying there, a couple of needed supplies), it was very cool since LA was very very very hot and dry during those days. Apart from living just upstairs, we have seen Chris only at our first day, for us this was amazing! We are very shy, and this distance was necessary to us in order to felt ourselves more comfy. Nonetheless, we are sure (she readily said that), if we had needed of anything Billie or Chris would appear both to help us or to give us any hints and tips we had asked for. Secondly, the place matches perfectly with the description, it is well located (at least for us it was, it depends of what you are planning for your won trip), and the neighbourhood is extremely quiet and secure. There is no garage, but there existed no problems in finding places for parking, indeed only one day we had to park 2 houses away from Billie's (almost nothing right?!).
I highly recommend Billie and Chris'. In our next trip to LA we'll, for sure, try to stay there once again.
