Kalvoya Island Tours and Activities

Very convenient location in central Oslo. Absence of any staff also means you have to be very vigilant when you punch in the code to enter the building. A suspicious young man snuck in right behind us when we entered. Was clearly not a guest as he quickly exited a side exit and prowled the adjacent alleyway for several minutes. We informed management online only to be told not to worry since the adjacent building was being painted. The young man we saw enter was clearly not there to paint.
