Despite Google occasionally directing you via some other route, take I-10 from the Tucson airport. If you are coming from the Phoenix airport, you must use I-10. From I-10; take the Congress/Broadway exit (258) East all the way through the downtown, until you get to 4th Ave. Turn right (South) on 4th Avenue and go 4 blocks to 15th Street. The Bakery is on the NE corner of the intersection. You can't miss it, it's a peach colored building that looks just like the picture. You can usually park on 15th street or right in front of the house. No meters or permits required. About the only issue with parking is an obscure rule. Don't park within 20 feet of the corner...Look for the faded yellow stripe I put on the curb, and stay behind that line. I don't remember this from the drivers license exam I took in 1973, but they say it was there.
