I had a great time in Rebecca&Seth's house! The room is clean with free bottle water and heater. Private entrance through the garage directly access to the room. The place is 15mins walk to BART, muni and wholefood store. Rebecca is very welcoming, she introduced me lots of tips for taking public transportation to attractions where I plan to visit, and offer to free use for their kitchen.
Oh, have to mention that their pet, Lola, is adorable! She likes to play with us.
If I'm going to SFO again, Rebecca&Seth's place is definitely my first choice!
