We visited Oslo for a long weekend and had a lovely stay in Grünerløkka. We came to explore the city and relish the Norwegian nature. I'm truly glad we did, and recommend everyone to do so. Our apartment functioned as a great home base, as it's close to both the city center as public transport stations that we'll bring to your for example Sognsvann or Holmenkollen. If we ever come back (and I'm sure we will) we definitely reach out again.
