Nice place, was here a few years ago and staying overnight was free back then, now it's €10 per night and via an app which is very annoying if you don't know anything about it. After trying many times I finally managed to get through, but instead of 1 day... I paid for 3 nights, €10.50 each time because the app didn't give a confirmation. If I had wanted 3 nights I would have had to pay €25.50, so I paid an extra €6 😡 Why no coin machine so everyone can pay smoothly?
