The Cosmo is a designer-hotel that prides itself on its staff's ability in guiding its guests to Berlin's most desirable experiences. In the museum quarter and near the bustle of Unter den Linden, it serves travelers who are a bit spendier than mid-range and appreciate minimalistic, sophisticated touches such as its floor to ceiling windows, illuminated room numbers, and the "bio-rythym" lights from designer Nik Schweiger, commissioned by the hotel for the lobby.
