Trine was a very helpful host - we arrived very late in the evening and left early in the morning but she was able to accommodate our schedule, and she had helpful suggesitons for where to go. We did enjoy the view of Oslo city from the mountain as she recommended us to do. We also really liked her apartment's location - close to many shops and metro (5-10min by foot) and park (5-10min by foot) and with easy access to other tourist attractions either by foot or by public transportation. The apartment had one full bed and three sofa beds (two of them in the living room), and one shower room (without toilet) and one toilet. The apartment could technically have up to eight people, but with only one toilet and given the two sofa beds are in the living room together, four would be the ideal number of guests for the apartment.
