We stayed at Go Hotel Osterport for a city break. Our room was very clean, the staff friendly and the hotel it's self is across the road from a train station which has a 7 Eleven shop and pizza place. The price of the hotel overall was good for location, room and facilities etc.There is also a large supermarket next to the train station. The hotel is walkable to nyhavn in around 20-30 mins, approx 20 mins to little mermaid. The area isn't very busy with people which we prefer (although the road between hotel and station appeared to be). You need to take a train to the central station as it's quite a distance away. The hotel is situated right next to the railway line, we didn't find the noise any real problem but some reviews posted this as an issue. The only main issue for us (albeit not a major one) was our room was right at the opposite end to the reception which is quite a walk down a long corridor which is spilt up with a couple of communal sitting rooms. We would stay here if we visit Copenhagen again, I would also recommend take the train from the central station to Malmo - very nice city and great train ride experience (10 miles across the sea)
