Nice place in the middle of Oslo. Martin is very helpful and in the room is everything you need. The only thing is, if you're traveling by car, first search for a cheap parking place because parking in the area of the house is very expensive. For 24 hours it costs 360 NOK. But if you keep this in mind there should be no problem because the house is easy to get to by public transport. If i'm not wrong, tram Line 11,12 and 13 do stop almost in front of the house. Thank again Martin!
