We stayed at Vidar's place for 3 days, and it was just what we were looking for. While the place is not in the centre of Oslo, it is a short Tram ride away, and the Trams are very regular, right outside the train station so we were able to get there easy enough. Once off the Tram it's easy enough to find, we just used maps, and it's about a 10 minute walk. The house is lovely, and has everything you need, the only thing I would say is that there are not curtains on all of the bedroom windows, and a towel covering the bathroom window, I would prefer there had been curtains on all bedroom and bathroom windows. Other than that our stay was lovely and would happily stay again in the future.
