This was a great place to stay! It has a great location with walking distance to the center. The appartment itself is beautiful, very welcomming and with a personal touch as the photos show. Beds are comfortable and the rooms/bathrooms/kitchen are clean. The balcony makes it extra charming and cozy. The hostess was on vacation, but she answered our inquiry promptly and we were welcomed by 2 of her friends, who were very friendly and helpful. They were so kind an even met with us at their lunchbreak from work to give us the key and show us the apartment. We also got tips on how to park for free approxamitly 300 m from the apartment, which was a surprise considering living so central!
This apartment made our stay in Oslo together with another couple very pleasant and a true treat!
Worth noting, though it wasn't an issue for us, you have to be able to climb 4 stairs to get to the aparment.
