The Brickell Arch condominium association claims Conrad Miami hotel owner Mast Capital Inc. tried to overcharge for shared-use facilities, such as elevators and the pool deck, and corridors maintenance, according to a lawsuit.

A joint venture between Mast Capital and New York-based investment adviser Angelo, Gordon & Co. paid $72 million for the Conrad in the Brickell Arch building in July 2017. The building is a 36-story development with luxury residential condos, the 203-room Conrad and offices.
