We stayed here on our honeymoon last July, overall it was an enjoyable experience.
The hotel was fine and the staff were friendy, we ordered roomservice on the first night and we got the impression that the staff member did not have an idea as to what he was doing. Firstly he told us that roomservice was finished for the day, we pointed out that it was down on the guest directory that it was not due to finish for another hour. At this point he took the order and served us the best shrimp salad I have ever had.
Stockholm is the most beautiful city I have ever seen and I will be visiting again.
