I enjoyed staying at Helen's place. The location is perfect for me as I had to travel to both SF and Palo Alto. It is just a few minutes' drive from SFO as described. Amenities are good and little things like bottled water in the refrigerator, ice cubes in the freezer, having both men and women's shower wash etc. show you they pay attention to details. Internet speed is very fast, over 300mbps!! Which means great for business travelers too. Mattress and pillow all very comfortable! The bedroom is not quite 100% blackout, but pretty close to 95% I'd say, which is great for sleeping in.
