This place is much better than I expected. Not only was the room immaculate and bright (sunlight most of the day), Katie provided a water heater to make tea and oatmeal, and light breakfast is included in the room. The location is very close to the 805 highway, convenient to the malls in Mission Valley, Chinese and other Asian restaurants 3 miles north in Clairemont Mesa, and about a 15-20 min drive to Mission Beach and nearby beaches.
Katie and her husband were very hospitable, open to some small talk, and Katie showed me where everything is (e.g. kitchen, lights, bathroom) and where are off-limits. Otherwise, I slept well and the room is quiet and relatively cool in the summer.
Thank you, Katie!
