We spent a lovely week here. Hotel staff were great and accommodated us showing up an hour early. The decor is wildly quirky - I felt like I was in the Red Room from Twin Peaks for a bit - but the longer we stayed the more it became clear that there was real thought and care put into all of it, and it tied in nicely to the surrounding neighbourhood and its people. A coffee table book commissioned by the hotel shared stories of the area and helped give a deeper sense of the place. Everything was set up in a fun way, right down to the rotary dial phone. The bed was comfy and the wifi was quick and reliable.
Location can't be beat, you're steps to transit connections to anywhere you could want to travel in or outside the country. Great restaurants at all price points nearby. Street-facing rooms have some noise - it's Europe's busiest rail station after all - but surprisingly peaceful most of the night.
There are some quirks you might not like - USB chargers only on one side of the bed, bathroom light can't be turned on without turning light on in the room, shower has little privacy and can be seen from the bed (IDK maybe that's a selling point for you!), but I loved my stay here and would 100% come back, or stay with this chain in other cities in the future.
