We, a family of four, stayed two nights at the Hotel Nebo. On the plus side, the staff were very friendly and helpful, and the hotel is in an excellent location, just a few steps from central station, but we didn't find it at all noisy. There are many great restaurants nearby, and a handy 7-11 on the corner. The negatives were the size of the triple room - really small for two adults and a child and an infant, and the beds were springy soft, or board hard. Advise bringing your own pillow, too, as the feather pillows we all found hard to sleep with. Shared bathroom was no issue - it was kept clean, there were several showers and WC's. Breakfast was a good deal - typical continental breakfast, of cereals, bread, meat, cheese, egg, juice etc, plentiful and cheap. For us, as a family, it was more central and quieter than staying at a hostel, and even a little cheaper.

The hotel is very well located short walk from the Central train station and an easy walk to all the sites in Copenhagen. The breakfast was excellent good choice of breads, cheeses, etc. Very friendly and helpful staff. We had a room with the shared bathroom. The room was neat and clean, we overlooked the back courtyard so it was quite for sleeping. Given the prices in Copenhagen this was good value.

Just 30 seconds from Central station and a short walk from Tivoli - this is a great place to stay in Copenhagen on a budget during the Xmas markets! The staff were friendly and helpful and the rooms were great for the money we paid. They were not too small and they were warm despite the cold outside.
The bathrooms were shared but were always clean. The breakfast was good too but you can also go to some nearby restaurants if you want something different. It's only a 5 minute walk to the main shopping district.
For how cheap it was - it was a perfect stay for us on a budget. We spent our money at the Xmas markets and other activities instead. If you want a decent stay on a budget - this is the place!

Stayed at Hotel Nebo for one night. First I must say that the location is great, just a few minutes from the trainstation right in the middle of Copenhagen. Also it´s very priceworth. But you get what you pay. The room was very small and simple. But it was very clean and the bed was comfortable. The showers and the WC is outside the room but it was quite OK and was kept very clean. The breakfast was rather basic but allright. The staff at the hotel were friendly. The only negative was that when people talked outside my room it almost felt that they were inside my room and that I woke up in the morning because the man in the room next to mine snored (thin walls). But all in all, this is a hotel I can recomend if you want a hotel in the center of Copenhagen and just going to use it for sleeping. And to a good price.
