Top notch! Maurizio is an awesome host - very responsive and helpful. The location is fantastic - lots of restaurants nearby and two grocery stores (note: the Rema 100 is better than the Coop). It's an easy walk to the Opera House and to the train station (unless you have luggage, then take a taxi) and nearby shopping areas. The apartment is very well maintained and is clean, modern and bright. We had plenty of space for our family of 5. The bathroom is very large (especially by European standards) with a nice shower. The porch is a nice touch as well. We can't say enough good things about the apartment and Maurizio as a host. If we return to Oslo, we'd stay here again!
