We enjoyed our stay in Per's apt. The airbnb is cozy and comfortable with plenty of room for a family of four. Tram number 12 or 13 (very short walk) was an easy ride from downtown Oslo and further out if needed. The apt is close to lots of cafes, restaurants, shopping, etc. We especially liked eating at The Kasbah...yum! I would definitely recommend Per's apt to anyone travelling to Oslo.
