We booked this hotel while in Oslo, as we wanted to move to a safer location (from Thon Hotel Spectrum) We got great rates on the room, staff were friendly, the location is very central, right beside the tramline and walking distance to the Palace/ city / restaurants etc. The room was modern and very clean. The buffet breakfast catered for all needs and was fresh every morning, with the option to buy a packed lunch which you make yourself from the buffet.

Good value for money (especially for Oslo!) and convenient location. A bit disappointed as we chose a "superior" room based on the photos from the hotel's website showing a sitting area. The room was actually much smaller and there was no sitting area. We asked for a room with a balcony and were given a room on the first floor overlooking a side street. We stayed over Christmas and there were very few guests in the hotel, so would have expected to have been given one of the better rooms. The room and bathroom with modern fixtures (shower only) were impeccably clean. Nice to have the heated floor in the bathroom during winter. The breakrfast is wonderful with a huge selection of scandinavian fare (smoked fish), fresh fruit salad and the lovely surprise of a "shot" of a freshly made smoothie (with fresh ginger) and delightfully presented verrine with cereal, fromage frais and raspberries. There is a choice of scrambled or fried eggs with bacon, sausage and potatoes. The staff at reception and in the restaurant are efficient and friendly. Oslo is a very expensive city - the Holberg is great value for money. We would discourage anyone considering visiting Oslo at Christmas. The city shut downs completely. If you are not in one of the big hotels then there is no where to have dinner - all the restaurants close for Christmas eve. A few of the convenience stores are open so you can get a sandwich to take out, not our idea of a Christmas Eve dinner.

My favorite and first choice when it visiting Oslo. I do not know why, but it is a small hotel, very good breakfast, friendly staff, smoking rooms or with balconies. Theu have what i need simple as that.
Maybe I should not recommend this hotel, because there maybe never have rooms available when I come to Oslo.
Stay and try:)

The location of the hotel is in walking distance to the city center and the tram also stops just outside the hotel. (Airport bus also runs from the hotel across the street). The room was quite small and cozy but clean and OK. The breakfast buffet was good, with a lot of fruits and service minded staff who cleaned the tables fast. The coffee and juice was terrible, but very much as expected when you have stayed in Norwegian hotels before. Didn't notice any noise outside except the tram passing by.
