My girlfriend & I stayed with Udi for about three weeks after returning to LA from an extended trip overseas.
Pros: Udi is a super nice, laid-back guy and was very responsive when we had questions or concerns throughout our stay. The location of his house was also perfect for us, because it was walking distance to my office and neighborhood has lots of good restaurants and grocery stores nearby. Even though the house is near a big intersection, it's far enough away that the street is quiet. We liked that Udi had the house cleaned weekly, which kept things looking pretty good. We also appreciated that Udi frequently shared his tasty Middle Eastern-style coffee with us in the mornings.
Cons: The roommate situation was a little nutty. Beyond my girlfriend & I, there were 3 other Airbnb guests staying there (including 2 sleeping on the couches in the living room - which we didn't know would be rented out), as well as Udi's roommate, and Udi himself (staying in the back house). This made the bathroom / kitchen situation a little crazy, at times. All the people around also exacerbated the noise issue in our bedroom. The room is "private," in that it's not a shared space, but it's definitely not "quiet," especially when people are using the kitchen. For people bringing a car, be aware that it can be tough to find street parking very close to Udi's house, but we were usually able to find a spot a block or so away. A couple other minor things: Udi's place doesn't have a working central heater, and space heaters were causing fuses to trip, so the house was really cold for the first couple weeks. In the last week, we were able to plug a heater into an outdoor outlet and run a wire into the house, so that made things better but it's something to be aware of if you're also visiting in the winter. Lastly, Udi's washer/dryer work, but the doors were broken and jerry-rigged with zip-tie handles, making me a little nervous I was going to get stabbed with a jagged piece of plastic.
Overall, Udi's spot is a more-affordable, decent option for people looking to rent a room on the west side
