I stayed in Cecilia's place 4 days. It was great, and I recommend the room to anyone: pleasant, clean, light, big patio right off the bedroom.
There's a refrigerator with some drinks and basics to put your own breakfast together if you want.
Bernal Heights is an interesting, funky area. A few blocks away are a number of good restaurants and cafés. I ate breakfast every day in the "Moonlight Café,"--very good. Bernal Heights Park is nearby, and from the top you get a huge view of the city.
Cecilia and her husband were helpful and cordial.
All in all: highly recommended.
