A decent place to stay in Oslo. Apartment is nothing special in terms of how it looks but it has everything you need for a weekend and the location is really fantastic - right in the middle of the Vulkan complex with loads of bars and restaurants and the food hall (Mathallen) right on your doorstep. Grunerlokka is just across the river which is also great.
I would say that this apartment is best for 2 people or 3 people max, however, as the second double bed is a a sofa bed and not very comfortable for 2. The apartment is general is very small but perfect for a weekend for a couple or 2 friends. Lovely little balcony as well :)
