We would definitely recommend this spot. It was very clean, comfortable, and the location was great. We could walk down to the pier, lots of shopping areas, and restaurants very easily. It was also easy to get to other parts of LA from this spot, either by car or public transport. We rarely hit any major traffic, as there are lots of options for getting to and from this spot.
One thing I'll mention, because I saw it in other reviews, is that the elevator was not working the entire week we stayed. This meant a lot of climbing stairs. We were fine with that (though it would have been nice to have an elevator on the days we checked in and out), but if you need an elevator for access you should ask if it is working.
Overall we had a great vacation. The apartment is well represented in the photos and description, and the host (Julianne) is very responsive. She typically got back to us within an hour of any communication. If your stay overlaps with the Santa Monica Farmers Market (Wed. or Sat.) I'd recommend swinging by for some nice fresh snacks you can have on hand for the rest of your stay.
