I just spent the last 3 and a half weeks at this house. (Halloween 2017--Thanksgiving 2017.) The location is superb--it is literally a 30 second walk down the street to the beach and the Dog Beach in Ocean Beach. (A fantastic dog beach where my pup loved walking along the beach.) Ocean Beach is a very laid back, "beachy" town. There are great restaurants and bars just down the street (approx 5 blocks) from the house. It is very dog friendly; I brought my dog and could take him to just about every store and restaurant in the area. It is also a stone's throw to the largest concrete pier in the US. You must also check out the farmers market on Wednesday evenings! The neighborhood is relatively quiet with just street noise from people heading to the beach. The house is close-by other hot spots in San Diego, too.
The house itself is quite nice. It has everything you could need--a dishwasher, laundry facilities and plenty of cookware. The appliances all appear to be relatively new and in great condition. The house has both cable and wifi, and although I had some problems with both at the beginning of the trip, Emily (the host) was fantastic about promptly fixing them. If you have a car while staying at the house, street parking can be a bit of a hassle in the evenings. (As is the story with most of California!) Also, they sweep the street on Wednesday and Friday mornings (one side each day), so make sure you pay attention to that. There is currently an open lot next door to the house and for the first week I stayed there were construction people in the empty lot. (Make sure your shades are shut as neighbors are very close! However, a privacy fence was put up.) They were not there the remainder of my trip.
Emily herself promptly responds to messages and takes action when things need to be resolved (see above comment). Emily also provides dish soap, laundry soap and other necessities for the house. She is also great about giving tips to activities going on around the neighborhood.
I would highly recommend staying at this house and in this neighborhood for your vacation in San Diego.
