Ragnhild's apartment was a comfortable home base for our couple days in Oslo. Clean, quiet (except on Saturday night when people were loud on the street outside), central location for walking and on a bus route (#34 or #54 to Møllerveien stop just a block away). We used the kitchen quite a bit, buying groceries at the two markets close by. Used the washer/dryer (used google translate to read the directions which where in several languages, but not English. Recommend air drying your laundry if you have time. Dryer takes forever and isn't kind to clothers.) Wifi worked fine.
Bedroom has just enough room to get around the bed, which was comfortable. We kept our luggage in the living room area during our stay.
We highly recommend Ragnhild's place for your stay in Oslo.
