Loved Circus Hotel! Great location, close to everything. Really good food around and great cocktails at their bar. They take care of every little detail, all the amenities et. They also have a private rooftop area for hotel guests.
The staff is super friendly and willing to help. Everything is spotless clean! The only thing I would comment on is the fact that the bed sheets were not the softest and had a lot of pilling.
Overall, I would definitely stay there every time I’m in Berlin!
