I was in this B&B in October 2011 for 2 nights. I chose it mainly for the beauty of the building, I liked it. When I arrived at the hotel the reception was empty, but they had left me a welcoming note, saying also that the key was in my room. So, I haven't had any problem. Free wireless without access code was good, worked properly. Heating is OK. My room on the ground floor was small but clean; wardrope, bed,table,TV were enough for one person. There were a few channel on TV in their language. B&B is very close to one of the main attractive places of the city(Vigeland sculpture park). But one should keep in mind that it's about 1 hour far away from the city center by foot. For me it wasn't a problem, I like walking and the way to the city center was on the main shopping streets of Oslo. If you don't want to walk so much you should use bus&tram. After reading breakfast comments here (yes, only cereals, milk,juice) I have eaten my own breakfast. I don't understand anyway why they are not improving the breakfast. The cost is high with respect to zillion equivalent place in the world, but it's OK when you think that you're in Oslo.
