very good stay in Oslo with my son - 12 years old -. He enjoyed the mezzanine and was able to stay in bed in the morning. I had also excellent night in the sofa and was able able to wake up earlier.
The apartment is very well located in a lovely residence, calm and all is accessible quite easily by walking or just in few minutes by tram/bus.
You can keep your eyes closed and go directly at Jo's apartment, he welcomed us very well and did everything to make our experience as better as he can.
Thanks and I looking forward going back with my wife to discover Norway by her side.
