This was a great place for our large group. It has proximity to the beach, some beach items on the lower floor, a cool outdoor area, an outdoor shower/garage bathroom, and it was very clean. There are 6 twin beds, a queen and a king + a couch that can sleep 2. There were also fans in the closets, which our group appreciated.
You have to go to the office to get the keys, which is slightly inconvenient, but it's on the way to/from the airport or train. The house is also close to the other houses in the area, so you're very close to the neighbors, but that's just the nature of Pacific Beach.
I don't think you can beat this place for the price if you have a large group like we did. We did a lot of research and booked 3 months in advance, and I don't think there would have been a better option that didn't cost substantially more. Would recommend!
