Good agent who upgraded the car for us given that our luggage did not fit the original reservation. Hotel Valo is a bit far and they do not have a collection of car to choose from.
The best rental car company in Kaarela, Helsinki is HERTZ with an average rating of 0.0/10 from our users.
Typically, how long you can rent a car for depends on the inventory of the supplier. For Kaarela however, it is certainly possible to rent a car for an entire month.
