Hotel 13 was in a very convenient position for us as we arrived quite late from the Oslo train and it is easy walking distance from the station. The room was at the back of the hotel, so was quiet, but very dark as the bedroom had no windows, only the en-suite did. However, it was comfortable and clean. There were a couple of issues with the en-suit. The shower drain was, I suspect, partly blocked and the shower door seal leaked, so water spread all over the floor. Secondly, the toilet door (sliding type) didn't slide because it was damaged at the top. Not issues for a one night stop but would have been if we were staying longer. We reported the issues to the management. It's a very convenient location for accessing the shops and eating places in the city centre. The breakfast was plentiful and very good. However, what we were charged for one night was more than Expedia quoted us and I will be contacting Expedia about this. We would certainly stay there again.
