Stopped by at Sarah's place for one night before our flight home. The location is excellent, a quiet area just over the road from the botanical gardens and a 2 minute walk to Tøyen underground, which housed a small shopping village with restraunts and shops. I'd say it was also within 20-30 minute walking distance to the centre of Oslo, including the Central Station. Sarah and her partner were super friendly and gave us some great tips for our last day, would definitely recommend!
