Nook is a hotel chain that provides studios for travelers. This particular one was in a great location in Mitte, Berline. Though it's quite in the thick of things, it's actually on a quiet street. I was able to walk to all the major attractions and also found lots of places close by to either get a bite, coffee, or purchase food.
Though this was in some ways beyond the control of the host, I do want to note that the walls of the studios are paper-thin. There was an unruly family on my floor whose child kept screaming at the top of his lungs out of anger over something. The family also kept slamming doors and cabinetry quite early in the morning. I immediately wrote to Nook, and it turned out that none of their staff were actually on hand to deal with the matter.
With regard to another issue, while it was smoothed out eventually, Nook were slow to respond to my request to book an extra night. This involved a LOT of unnecessary back and forth that really could have just been taken care of with more diligent customer service.
All this said, I really did have a good stay at this facility and can recommend it to others. Just maybe bring earplugs!
