Martin's place is a great Oslo location. It's a 15 min walk to City Hall (where you take the ferry to Bygdoy), 30 min walk to the train station and a short 5 minute-ish walk to the tram that would get you to everything. It's also a few blocks from the National Theatre train stop where you can pick up the Flytoget to/from the airport and trains to the Oslo central station. There is a market in the bottom of Martin's building that had all we really needed and a bigger market with a pharmacy a few blocks away. Martin's place is very centrally located and one of the cleanest Air BNBs I have seen. It was spotless. It's on a quiet block in Frogner and the balcony/terrace has a nice view over to the Fram Museum on Bygdoy. It was nice to have access to a washer/dryer and dishwasher and a full kitchen for cooking. The building is quiet, as is the neighborhood. I highly recommend Martin's home.
