Angela's place is tiny, but just fine if you need a place to crash while spending most of your time exploring the city. It's a bit of the beaten path, but an easy walk or ride to the Mission, from which point you can keep walking or take
BART or Muni elsewhere.
The details and thoughtfulness really made this a great experience for us. There was coffee and tea provided, even three types of milk in the fridge for the coffee! And since Angela knew I was traveling with my son, she left out a couple of coloring books and puzzles for him. She checked in with us when we arrived and followed up with me when I forgot something.
My one recommendation for travelers is that, if you want to go to sleep early or sleep late in the morning, and you are noise sensitive, bring earplugs. I always have mine with me, so this trip was just great.
