The flat is located right in the new and modern Barcode district. It's only a five minute work to the main train station and for visiting all the famous places in Oslo downtown,you don't even need a train right, everything is right next to you!
The check in is totally flexible and if you follow the provided instructions,it's not difficult at all.
You will find a really nice,modern and clean apartment that's still spacious enough for a good movie night!
10/10 can recommend!
