I stayed one week in Alexander's flat with my parents and my children. The first floor flat is spacious, nice and well equipped (including Nespresso, fridge with ice, washing machine and dryer). There are a large kitchen/dining room, a large livingroom, a double bedroom and a smaller one with a loft bed. There is also a nice balcony and a communal garden (we did not use it, but it was very good to see some green). The location is ideal for visiting Oslo (and for going to the University of Oslo). The communication was excellent. I absolutely recommend Alexander's flat.
