The place is very easy to find but you may get confused with two other buildings that are close by. Parking may be a bit of a hassle depending on what day and time you're there.
Despite the small issues the coffee and breakfast is definitely worth driving around the parking lot on a Saturday afternoon! The choice of beans they use for their espresso have a rich, bold and intense flavor that'll leave you wanting more.
I live in Tempe and the drive there is definitely worth it. If you're coming alone, bring a book, you'll look like a regular.
