This was my second stay at this hotel. It is by far the finest Westin hotel in my experience. It is perfect in nearly every regard except for two minor points. Finding a room with an electrical outlet by the nightstands was a challenge and had to be rigged with an extension cord. Second, I could not use mirroring off my iPad to the flat panel TV.
Otherwise, the in-room refrigerator, coffee maker, great linens, towels and amenities were terrific. It's very pricey, but it's Palo Alto, CA. The service makes up for it. I was impressed that the pool was comfortably heated at the end of November.
