Gerson and Jim are simply wonderful, and staying with them is the experience that I think Airbnb intended when it was created. You feel like you are staying over at your friend's house. It wasn't just using a room in their house for a couple days - on the contrary, they invited us to go out with them, warmly welcomed us to lounge around their backyard/house with their other friends, and even shared some food and drinks with us. By the end of our 2 night stay we felt like we were with good friends and not simply an airbnb host. But it isn't too overwhelming either -- I'm sure that if we had preferred to keep to ourselves and the room, they would have absolutely respected that too.
As for the house and room -- it is beautiful and clean. The bathroom is spotless, the bed is very comfortable, and their backyard truly does feel like an oasis. The house is also a quick ride to/from the airport and Universal Studios. It's very inviting and made for the perfect airbnb stay.
