Hotels in Norway are expensive. The price may be well over 100 euro per night per room during peak season. The hotels in the suburb are much cheaper but you need to take public transport, it is time consuming and expensive. So if you are just stay for 1 or 2 nights, try to stay in the centre if you can. Bergen Budget Hotel is fairly new, their room is like a mini apartment with cooker, microwave and refrigerator. But this hotel has no attendants, "EVERYTHING " is self service, include check in. So if you have questions want to ask, tough luck to you. The big plus of this 2 stars hotel is the location, its walkable to train station and the Harbour, and many restaurants and supermarket nearby, wifi works beautifully. Their prices change constantly, my rate is 60-70 Euro per night, so its not too bad
