"City Box is a basic hotel but it's clean and central to Oslo. Some of the fixtures and fittings could use an upgrade, the bed/mattress was a bit basic and creaky and the shower head could have been better, but if you're only resting your head then that's not a huge deal.
You check in with a code (that I didn't have because my email service was being slow), but there are helpful staff on hand if you need help. And all the staff I saw were polite and friendly.
The hotel has a partnership with a few nearby eateries and you can get money off breakfast or dinner, though I didn't use any of them. At first glance they still looked a little pricier than I, as a cheap backpacker, wanted to pay. Maybe I should have looked harder as I did find food prices in Oslo to be high anyway.
The hotel is extremely central in Oslo - 5 minutes walk to the train station - and there are many choices of shopping, eating or visitor attractions close by.
It is a hotel I will look to use again if I return to Oslo."
