Great stay and PERFECT beach weather. The space is a little smaller than what it appears in the pictures but comfy and cozy. The space is best suited for a couple or possible a family with small children. Outdoor space is a definite plus but it has no covering in case of rain.
The location is directly on a corner next to busy Mission Boulevard so you will have street noise. (We live in a city so it did not bother us) You have to cross the street to get to the beach. We did not have any difficulty doing so but may be a consideration for others. You can walk directly to the bay side with no street crossings but it is definitely not as desirable a spot except if windy.
There are no nearby grocery stores but a couple of liquor stores that carry a few basic items. For walkable restaurants, try Miss B's, Rosaria Pizza, La Perlita, Olive Cafe, Olive Baking and Better Buzz Coffee. About a mile or so North in Pacific Beach, there is a grocery store and numerous restaurants and shopping.
Overall, great stay. Next time we will probably pay a little more and pick a rental that is directly beach front or at least not right on the main thoroughfare. It was clean, had beach chairs, towels, bikes and beach toys available. We did rent a beach umbrella from a place just up the street for cheap and they had numerous items available. Can't promise you as great of weather as we had but it is a great location if you are looking for a quiet beach with not a lot of "extras".
