if you want to avoid headaches and missing appointments, do not rent a car with Greta. It really looks like she does not care about the time proposed by the app. I intended to take the keys at 7:30 am but she decided to show up at 10:04 am only. In sum, after 3 hours of waiting, her brother brought the car to me at 10:40 am. I had a reservation for a tour west of Austin planned 2 months in advance, but her delay ruined everything, I spent money, time and patience with a relapse host.
