Availability first
A parking label does not guarantee a free space. Ask about reserving one and where to enter. The garage entrance can differ from the reception address.
Compare the full cost
Check the daily price, when the parking period starts and whether you can leave the car after checkout. Do not assume parking is part of the room price.
Dimensions and charging
For a large vehicle, confirm garage height. A charger, its power and availability are separate questions: an ordinary parking space does not provide charging.
