We would definitely recommend staying at this condo. Our family of four (with two young children) met up with another family of four for a five-day beach vacation. The condo was clean, bright, modern, and only a quick two-block walk to a great beach and the boardwalk. The owner had provided a lot of thoughtful extras, including paddle boards, bicycles, beach toys, a beach umbrella, and a kitchen with all the necessary pots and pans and utensils. We also enjoyed the barbecue on the patio! There's no A/C, but the breezes and fans keep the place cool. It was also a fun area, with tons of restaurants, cafes, and other places within easy walking distance. The only slight con for families, that's of no fault of the host: Pacific Beach is a young, lively area, and there's a club across the parking lot from the condo that has a loud bass beat on weekend nights. Wasn't a big deal for us, and you could only hear it from the front bedroom, but if you're a very light sleeper, would recommend ear plugs or sleeping in the back bedroom.
Even with two families, we had plenty of space (the high ceilings make it feel even bigger), lots of closets and storage to put stuff away, and comfortable beds and really, everything we'd need for a stay.

Overall, great place for friends or extended family to stay, near beaches, parks, Sea World, and restaurants. We had a wonderful time, and the host was a pleasure to work with -- responsive to our questions, provided us with a Google map of her neighborhood favorites, and easy to contact.
