I travel often for business to San Francisco. This is my first time staying at the new Loews Regency (which was formerly the Mandarin Oriental). The staff was incredibly friendly and accommodating. My room was on the 47th floor and the views of San Francisco and the Bay were stunning! The fitness center is also equipped with Technogym equipment which is my favorite. I didn't get an opportunity to use the spa because of my schedule; however I took a brief tour and I was so impressed that I will make a point to have a treatment in my next visit.
And.... Wifi was also complimentary!
