My stay in Calma Berlin Mitte hotel was nothing but perfect! The location of this place is such an advantage for people visiting Berlin for first time. Walking distance from many Berlin's top attractions. Even if you are heading to something out of city (e. g. Potsdam) there is a plenty of options for public transportation around. The room was super clean and they were checking every day for the need of basic amenities. The staff was always very helpful. The only thing which I might take in account was the price. It was a little bit higher than expected but maybe it is my bad as I haven't traveled since pandemic start so, who knows - maybe that is the new normal. Anyways I want to thank Calma Berlin Mitte for the pleasant stay! Cheers :)
