Absolut beautiful flat in a very nice location.
The flat has everything you need to stay in Oslo. Norhing really to say about it, it is just perfect.
A lot of Restaurants are around and walking by foot to the different sightseeing spots is really easy.
The only "difficult" thing, but this is the case for Oslo in general and not linked to this place is trying to find a place to park your car.
There is a parking house just a 2 minute walk away, but not really cheap.
However, the location, the flat and the communication with Maria was for us 100% positive and we can completely recommend this place.
