The host is very helpful and the area is perfect for visiting Oslo.
There were, during my stay, some negative things however.
It is good to know that the room is in a flat with several other rooms and with only two bathrooms. At different times of the day, especially between 7am and 9am it is very difficult to access the bathrooms. And it is really very annoying.
It would be good to consider it as a student residence rather than a coliving solution. It is good to know this before booking.
