We booked the Meininger as part of a girls weekend to Amsterdam. We were really pleased with the price compared to other hotels in the city and the hotel looked safe too.
The Meininger is only a 5 minute train journey from Amsterdam Central which was super convenient. The staff were really helpful and spoke good English which made our stay a lot easier too.
The room was quite small but fine for what we needed. We were quite impressed with the "split bathroom". The beds aren't great. They were quite uncomfortable and the pillows were far too soft. The bed on the top bunk also hadn't been made up and it was really difficult for us to make it up so that made for quite an uncomfortable stay for the person with that bed.
Overall though, for the price we paid the hotel was ideal.
