Great, happening part of town. Kind of crazy on Saturday night, but I enjoyed walking around and the energy. I attended a concert on Sunday night and it was only 2-3 minutes away from the apartment. There are quite a few concert venues in the area. Also, super easy trip to\from the airport, about a 10 minute walk to the train station.
Steffen was very responsive with any questions I had and quickly worked with me to spend an extra night when my flight was cancelled.
Bonus to the area - my friend and I went swimming by the Opera House, Oslo Bay, Norwegian Sea. Absolutely wonderful pre-winter swimming - they also have saunas to reserve in the bay area. About a 20 minute walk - also the Munch museum is right next to the swimming area.
The apartment is clean and cozy. I didn't cook but the kitchen appears to be well-stocked. The bedroom is next to an inner\private courtyard so it is quiet. I highly recommend.
