Justins space is 2 blocks from the beach (about a 6 minute walk), really well-decorated, and has great amenities. It was clean when we arrived (as opposed to many other reviews that stated it was dirty) but we still sanitized everything, just in case with COVID :)
The layout is pretty funky with a studio downstairs without AC but otherwise everything was really nice and the apartment was pretty big with a ton of space (especially for us to WFH!)
The only downside is that the area is a little bit seedy. We walked around the neighborhood and there were many homeless people. It's on the border of Venice and Marina Del Rey so it has a bit of a seediness to it if you're okay with that. I'd just avoid going out at night and stick to the beach if you can...
