We spent two nights here. Arriving at 6pm, our room was practically in the lobby and the window for which we paid extra, looked onto an ugly inside passage. I noted it was an unattractive room and we were moved the next day to a nice room with a small balcony and view of the canal. I felt we paid for this and didn't receive it the first night.
Overall nice play to stay. Fairly convenient bus and tram connections to museum and train station.
Front desk folks very agreeable. Avoid lines and buy museum tickets at the front desk. Nice breakfast saved time in morning but not special.
It felt like running a gauntlet to enter hotel with always several smokers puffing away on the steps. I wish management would instruct guests and workers to walk across the street.
