Sigvart's apartment is just as shown in the pictures. Clean and stylish, located in a great area. The apartment is just by the Mathallen food hall with lots of choice for tasty food and drinks. It's also only a short distance from the central area of Grunerlokka which is where you can find cafes, bars and shopping (all very hipster!) Oslo is also much smaller than we had anticipated and though the apartment looks a little distance from the centre and museums etc, it really is just a 15/20minute walk.
Would recommend this to friends as a perfect base for a trip to Oslo!
