I was pleased with this hotel for the price. It's a little bit away from the centre, but not a problem if you have a bike or don't mind taking a stroll.
I've previously stayed in hotels in Copenhagen around the same price, but Hotel Sct. Thomas was the best in terms of cleanliness, friendly and helpful staff, as well as nice setting. The room was small, but it was in good condition and for the price, you can't expect much more in CPH.
Would stay there again.
