We've stayed in many airbnb's, specifically in L.A. for work. If there ever was a tutorial on what all airbnb's should look & feel like, this would be the place. It's simple, cozy, great value, good location, clean, the owner is easy and everything is simple.
The best part is that there are many little details that make SUCH A DIFFERENCE when you are there for just a few days and don't have to bring & buy every little thing for your stay. It really doesn't take that much more money to add these details and do things right but It does take a bit of care ;-)
