Nice flat with a nice view, with a few not very serious but yet annoying things:
Be aware that there is nothing at all in terms of salt or pepper, coffee or tea. You need to buy everything, which adds to the cost.
Maintenance not tip-top. A light bulb needed replacing in the bathroom, the drain of the sink in the bathroom was blocked, the floorboards in the flat are not properly fitted, so they move and suddenly leaves gaps.
There is a careful description of how to sort rubbish but not the coloured plastic bags to use for two of the categories.
There was a false fire alarm (this often happens in Norway) in the middle of the night. I apparently was the only one able to understand the instructions on the alarm box, which are only in Norwegian. I also knew how to reset the alarm and silent it, but the available master key you need to do this was broken!
Otherwise a tremendous flat and one of the nicest places to stay in Tromsø (and I know most of them)
