We stayed at Katie's our last night in LA. The location is perfect if you have a car, as it is not in the city center but it is a nice, clean and safe neighbourhood.
The room is very good: spacious and it has a microwavw, a fridge and some other amenities. I'm giving it a 4 out of 5 only because of the bathroom: it was sparkling clean and the shower was great, but you need to enter the main house through the living room and I didn't want to disturb the family!
We would definitely repeat with Katie and William :)
