Maurizio provided excellent communications and was very willing to answer questions and provide help. We had an issue with about 15 kilos of wet laundry hung up to dry in the flat. Maurizio removed them, promptly. More problematic: I had an allergic reaction to something in the apartment and I suspected that a cat had once lived on the sofas. Maurizio insisted that there was no cat in the apartment, but I needed to be on allergy medication the entire stay. Every time I left the flat, my asthma and sneezing cleared up. To Maurizio's credit, he did volunteer to relocate us to another apartment. If you have a cat allergy, you may want to confirm that Maurizio has addressed this issue. Otherwise, a terrific stay in Oslo!!
