"We recently stayed at The Thief in Oslo and it lived up to its reputation. Yes, it is expensive, but in our view it was worth every penny.
Our room was beautifully appointed and very comfortable, and the staff throughout the hotel were unfailingly helpful. Breakfast was a real highlight: a superb spread with excellent service, and the scrambled eggs were amazing. Dinner options in the rooftop restaurant are more limited, but what we had was perfectly fine, and the setting is lovely.
The gym is good and the spa is excellent, though be aware that spa access may cost extra depending on your room category, so it is worth checking when you book.
Highly recommended if you are looking for a luxury break in Oslo. We would happily return."
