Edwina and Art's place is a perfect stay in San Diego. Edwina was incredibly kind, which added to the ambience of the place. Even though you're staying in a room within their house, it feels like you're staying by yourself (barely see Edwina or Art). The location is quiet with a few fast-food restaurants nearby. For those of you who are traveling without a car, you may be at a slight disadvantage; however, there are ways to get around (non-car user here)
Applications to use for non-car users.
GoMTS, Compass Cloud, and MetroLink are important apps for you. GoMTS is San Diego's Google maps (travel), but specific to the City of San Diego and will help you get around the city. Compass Cloud is another app that will help you purchase bus/trolley tickets to get around the city. Metrolink is an app to buy train tickets to go between cities such as Corona, CA to San Diego. Tickets are cheap ranging from $6-14 dollars, give or take.
You can catch the bus/trolley near Starbucks (Palomar Trolley Center).
Exceptional experience, strongly recommend.
