Authentic, old, historical are all bad excuses for expensive below standard accommodation. No elevators, no telephones in the room (!) no easy access because of ongoing roadworks, bad quality linen and horrible pillows, bad taste all over, tiny old bathrooms. No airco, noisy street in front. Sleeping is a challenge. I am stopping here, it's too depressing for words. Stay away.
The restaurant is good though.
Can't understand why Frommer's lists this as one of their favourite hotels in Denmark.
