Great airbnb. Brendan and Stina are really nice, and so is Belmont. We checked in late and they explained everything to us so we could arrive whenever we wanted. They also let us leave our suitcases in the kitchen after we had checked out.
The room is simple and small but clean and comfortable. Even the mattresses on the floor were comfy. You will have a desk to store some things and a clothing rack for your clothes. The bathroom was clean too. The kitchen was a bit messy but that's what makes it look like a home and not a hotel. Brendan and Stina also let you eat their food :)
As mentionned in the comments and description the neighbours are really noisy. However, after a long day exploring L.A you'll be so tired the noise won't even be a problem and you'll sleep well.
The location is really good too but make sure to download a map of the metro/buses in case the red line isn't functionning and you don't feel like walking too much.
I totally recommand this airbnb, you won't find a better place for this price!
