The location is very central within Oslo, it is within walking distance for many major sights and there are plenty of bars, restaurants (and take away places), and supermarkets nearby. Anita is very nice and is happy to have a good chat and help you settle in for your short stay in Oslo. The room is exactly as described, it is a comfortable small room with a single bed, it was fine for the couple nights that I stayed there.
I would recommend this place for solo travellers.
