The stay was great, and the apartment has an interesting, cozy and pleasant layout to it, that the pictures don't capture. The kitchen really has all one needs for pretty much anything food preparation, plus a number of extras, coffee, tea, honey, and more - thanks Julia.
If you need to access the city (as in my case for work) it's very conveniently located with a quick walk through the bus terminal (great in winter) and you come right up at the central station.
But it's also a great location for a number restaurants as well as super markets around the corner. Oslo really is a great city and Julia's apartment makes the visit even better.
