Mario's place is awesome. If you're looking for a true Venice Beach experience, you've got it. You walk out of Mario's place and you are on the boardwalk. Everything you need is within a 3 minutes walk: coffee, breakfast, lunch, gym, parking, bike and surf rentals. The place gives you enough privacy even though it's literally on the boardwalk. It's also quiet and peaceful in the evening and at night which was suprising to us. Mario is also really helpful and will give you all the necesarry tips you need to get to know the area.
All in all, great value for a decent price. I recommend it and would definitely come back some time.
