Hyatt House; Good Stay!
Great service at this hotel. Check-in was smooth, the amenities were clear and we even had some help from housekeeping as they lent us some cleaning supplies to clean up our rental car after one of my family got sick. The room, booked through Hotwire, was not a suite, but very nice and spacious. The hotel appeared very clean and the staff extremely welcoming and caring. The free breakfast was good. Different hot items everyday accompany the usual cereals, breads, fruits, yogurts, and juices. Because the hotel had recently changed names, some things still called it the Summerfield Suites, but others the Hyatt House. They are continuing to change over to the new name. 
The only con I can think of would be our wake up call on our first morning came one hour early. The phone system had not been working right. We called the front desk, they said they would work on it and we could call them for a wake up call the next day instead of the automated system and they would be happy to give a call to the room. We did so, and had no problems our second and final morning.
My family would recommend this hotel to anyone visiting the San Diego area that doesn't mind being about 15-20 minutes outside of town. We had no problem driving to town for our whale watching tour and the zoo.
