I use to live a few miles from here and rented here one time a while back. It's on the corner of Pico Blvd. & Beverly Dr.. About 1 block south of Beverly Hills city limit. The Hertz office is right next to the exit of the parking garage. Small office. They had maybe 10 parking spaces for Hertz vehicles. This isn't a place where you can get picky about your vehicle. The day I rented they had a total of 4 cars. Their hours are even more limited now than when I rented (M-F 9 to 4). If it works for you, great. But don't expect much and with such a small selection of vehicles, they can run out even if you have a reservation. I'm a big fan of airport locations (especially Hertz LAX) because of that reason.
I hope this redirects properly to the picture of the outside of the Hertz office located inside the hotel. Hertz is located right below the 1177 on the building if it doesn't (see a Google street view).
