Easy to drop off but...
I did not like that when I returned the car in Innsbruck no one was at the counter and every other car rental outfit had a representative there. Hertz said they were open till 6pm, I was there just after 5pm (and my rental wasn't due until 9pm). Would be much nicer to check out with a person.
The length of time you can book a rental for is subject to the inventory of the supplier. When renting a vehicle from Dreiheiligen - Schlachthof it should be possible to rent a car for a whole month if needed.
