Just noticed that Sixt now has a location that shows up when searching for SFO. I couldn't find it when I had a look in november/december, so I guess it's been added quite recently.
Looks like it could be located at The Westin. Anyways, I'm renting a week in San Francisco in March and would just like to know if anyone has tried the location, what cars they have and upgrade experience.
It's quite a bit more expensive than Hertz for the dates I'm checking, but maybe that will change.
