Regarding payment options, Villa Siena is certified to accept Medicaid. Prospective residents and their families should contact the facility directly at (650) 961-6484 to confirm current availability of Medicare or private pay arrangements, as coverage options and bed availability can change over time. The facility's non-profit corporate ownership structure may also affect certain financial considerations, and direct inquiries to the facility are advisable for specific billing and insurance questions.
When compared to national averages, Villa Siena presents a mixed performance profile. Its overall 3-star rating places it at the national midpoint. The 5-star staffing rating is a notable point of differentiation, suggesting the facility reports higher staffing levels relative to national norms.

About CMS Star Ratings
CMS assigns 1–5 star ratings to Medicare and Medicaid-certified nursing homes based on three domains: health inspections, staffing levels, and quality measures. The overall rating is a weighted composite.
A 5-star overall rating does not guarantee excellence in every domain — inspect each sub-rating independently. Data is updated quarterly.
