Fan and Jason's guesthouse is adorable, clean, and perfect for a quiet stay in San Mateo. We booked it with intentions to fly out of SFO, but had to change to San Jose at the last minute and it was still very convenient. I've stayed in quite a few very clean Airbnbs before but I can honestly say this guesthouse was the cleanest I've ever experienced. Top notch amenities and very responsive hosts. Highly highly recommend.
