Zoku Copenhagen was excellent - not just excellent overall, but excellent in all the individual ways that mattered to us. The room itself is wonderful. The storage-solutions really are smart and effective, and the bed being in a loft-area really made the room feel like a studio-apartment that we were living in rather than just staying in for three nights.
There are many things about the place that could be highlighted, but to choose a few: we arrived 4 hours prior to our check-in time. Our room was ready, so we got to check in immediately. We've had other hotels charge us a fee for this - even though the room was ready and waiting for someone to use it.
Also, in a rare twist for hotels, the rooftop bar at Zoku have baristas who make good, proper, well-made lattes, and being able to get a proper cup made in the morning, take it down to the room, and have it while getting ready for the day is one of those small things that goes a long way,
All in all this place is cool, comfortable, relaxed, and homey in a way that feels perfectly natural rather than forced, and it's definitely somewhere we'll stay again the next time we visit Copenhagen. Highly recommended!
