You will feel very welcome chez Sue in San Mateo. The house is on a quiet and pleasant street minutes from shopping and restaurants. It’s also only 15 minutes to SFO and half an hour from downtown San Francisco.
The place is modern and clean. You share a bathroom with other guests (if the other rooms are occupied) but we always found the bathroom clean and available. The room furnishings are sparse but comfortable. I will gladly stay there again while in the Bay Area.
