The three of us had a great stay at Olaf's apartment. He sent us really clear instructions on how to get there from the train station and how to get the key which made check in a breeze. The space is lovely, light, clean, and warm with a great outlook over the courtyard. The location was perfect, too - nice and quiet but Oslo city centre is just a short (scenic) stroll through the park or a quick bus ride away. Highly recommended!
