This place is a wonderful beach location for 1-2 people. The space is very clean, with an excellent shower. The bed is FABULOUS. The kitchen comes with enough to cook some simple meals. It's literally a 2 minute walk down to the beach. It's a very quiet beach - a lot of surfers, but not tons of people all over the sand. The location is also very, very close to a lot of restaurants and coffee places. It's about 20 minutes from Mission Beach and the main boardwalk area. 25 or so for Ocean Beach (where the dog friendly beach is).
There were really only two drawbacks I found. One was that because the space was so small, there wasn't much room to dry all our towels, bathing suits, and other wet clothes. A drying rack would be nice. The other is that because the space doesn't have much in the way of windows, it got a bit stuffy. It wasn't bad at all in the 75 degree weather with a fan, but I could see it being sticky when the temperature goes about 85 or so.
Overall, I definitely recommend this place to anyone looking for something small right on the beach.
