If you're looking for the Venice Beach vibe this is a great location. The Venice Beach strand and neighborhood is more colorful, urban, some would say grittier so keep that in mind. It's not a Laguna or Newport Beach kind of upscale vibe. The actual beach itself is really nice and well maintained. The apartment is like half a block from the beach, 3 blocks from some restaurants/coffee/shops and about a 10 minute walk to the start of the "boardwalk shops." So the location is excellent for all that. We felt safe enough walking at night but I could see where if you're not used to more of an urban setting you might be a little wary. There are folks partying (not excessively) and there's a lot of pot smoking all along Venice Beach so you should expect that -- it's part of the vibe.
The apartment was clean and very comfortable. There is no AC but the overhead fans and a few open windows do a nice job. We were two couples and it fit well, especially if you're out most of the time which you'll likely be. Ian is very responsive. I'd definitely recommend the place and the host.
