We stayed here for a 3 night break in Copenhagen. I picked it due to the location - which was fantastic. In fact overall the hotel was excellent for the price: great breakfast, location, and very friendly and helpful staff.
The only reason why I didn't give this a 5 star is that the rooms are very hot and bed very soft, so we didn't actually sleep very well. The bed is obviously a personal thing (others may have found them very comfortable) but the rooms were very hot - which isn't helped by the fact that they are small. At night we had both the windows open and the fan on, but this didn't make much difference. However I doubt there are many hotels with air conditioning in Copenhagen, so this isn't a problem just for this hotel.
A couple of things to mention:
You can hire bikes from the hotel for the day (about 125 kroner). Highly recommend this - we decided to use them and it was a great way to explore the city. Copenhagen is very bike friendly, with most roads having separate cycle lanes. Also it was really good fun!
The reception can order a taxi for the airport, which is a fixed price - about 220 kroner I think. We had to get a taxi at 530am, it arrived really quickly and at that time of day only took 20mins to get to the airport.
I would definitely stay here again
