A nice apartment very close to the city centre, Karl Johans Gate, Royal Palace and other attractions.
Clean and simple in a nice neighborhood, close to a wonderful park (St. Hanshaugen), a store (Extra) and a number of cafés and services.
Slightly underqeuipped kitchen, although sufficient to prepare the meals you will need during a shorter stay.
Working washing mashine in the bathroom, extra equipment available in a common storage room (ironing board, iron, vacuum etc.)
Self check-in and check-out with convenient codes.
A little party noise in the street on the weekends but nothing unbearable.
All in all I recommend staying there - it is clean, has everything you need for a short stay and is well located.
