You really can’t do better at this cost bracket in Oslo. The host was so good to us. She opened her home up to us and upon arrival gave us detailed instructions on how to use the transit. She really went above and beyond. This place is an excellent choice for your stay in Oslo.
The location is less than a block away from the metro. I saw complains about the road noise but it’s nothing more than you would expect from being in the city. The location is not on a busy road or intersection.
