The parking of the hotel is nothing more then the drive beside the hotel. On the picture it is marked with 1. The owners don't call it a drive but a parking. The price is 5€ per day.
There is place for approx. 4 cars. All parked in 1 line on the drive. You have to leave your car key at the reception in case one of the cars in front of you want to leave. In that case the owner will remove all cars that are needed to "liberate" the car that want to leave. It's not a pleasant thought to leave your key behind. You never know what can happen and in case of a spare key: you can forget it when you leave with all effects.
It is not a closed parking so anyone can go on it as they like. Number 2 represents a public way to the beach. If you park to close to that side people can actually touch (or damage) your car.
If you park to close to the hotel then people can not passing by easily.
So it has the same safety as a public parking that is located near the railroad in the neighborhood but then it's free and you can keep your keys safe in your own possession.
Take also a look at number 3. It's the sunroof of the hotel and see what's on it. Or rather: see what's missing. But later more about this.
