My friend and I had a great time while staying at Lu's guesthouse. The house was spotless and everything was as described/pictured. The beds were very comfortable and, as other reviews have noted, the water pressure in the shower was amazing.
Communication was seamless -- Lu checked in with us a few times via the Airbnb app to make sure everything was going well. She sent us the gate code on the morning of our arrival so we were able to enter the property on our own, which was much appreciated after a long flight. It was also nice to not have to deal with another set of keys throughout the stay.
Coming from a city ourselves, we found the location to be the best of both worlds, being in a quiet, suburban area with street parking while still having direct access to the Metro line. It was handy to have the option to take a short train ride into Santa Monica or other neighborhoods if we didn't feel like driving.
We did occasionally hear some street noise in the mornings, so light sleepers may want to bring earplugs or a travel sound machine. But the noise was minimal, especially considering that you're in the heart of a major city.
Overall we had a great time and would definitely stay here again!
