This is a really great little studio. The description is 100 % correct, and Michael is a really friendly host who's really concerned about the well-being of his guests! In advance of our stay, he was always extremely quick to answer any questions we had. The check-in is easy and uncomplicated (the check-out as well) and the reserved parking spot spares you from searching a space for your car on the street, which would have been quite difficult. And we just loved the studio!
Venice Blvd, where the studio is located, is one of the bigger streets in Mar Vista, but the street noise is okay. After rush hour, it's just the normal noise that you'd have in any other city. The beach is very close by, you can even walk there, if you feel like it.
Altogether, we can only recommend that you give it a try and see for yourself. If we should come to LA again, Michael's studio would be our #1 choice to stay.
