This place is terrific. My family and another family flying in from Boston stayed for a week during Christmas. Other reviewers have hit the high points already and they were accurate in our case. The location is great for seeing the local popular attractions. The San Diego Zoo, Sea World, USS Midway, and Balboa Park are all 10 miles or less from the property (I'm sure I'm missing several other ones too; those are just the ones we saw). It's also a short walk from the property to the beach.
The house itself was perfect for us. There are three floors - bottom floor has a bedroom with bunk beds, second floor has 3 bedrooms and a patio and front yard seating area, third floor has the kitchen and living room and another patio with a beach view, and on top of that there's a rooftop with yet another beach view seating area and a hot tub. We had 7 people in our group and the property easily had enough space for us. Nice amenities too. There's an Alexa controlling the stereo, which was neat, as well as the aforementioned hot tub. Our host, Alain, also left several nice touches, including tips on local attractions and restaurants, and bagels waiting for us upon check in.
I'll second the other reviewers who mentioned the stairs. 3 floors + a rooftop = lots of going up and down stairs. If you have someone in your group who isn't physically up for that for any reason, this property might not be for you. They weren't a problem for us though and if anything they were a plus - having multiple floors breaks up the space and makes it easy for someone to grab some quiet time while the rest of the group hangs out elsewhere. We had a great time and I'd gladly stay at this property again.
