I must echo the other reviews: the pictures do not do Lene's place justice, it is much nicer in real life and provides the most stunning view of Oslo; a quaint and very stylish apartment.
The location is great in that it's in a quiet neighbourhood but is no more than 15-20 minutes away from the city centre by public transport or taxi. Lene herself is a very easygoing, kind and communicative host - check-in was super easy. I would definitely stay here again next time I'm in the city; thanks again, Lene!
