This amazing penthouse located in Frankfurt, Germany, spotted on Sotheby’s and is available for sale for $5,146,477. This fully furnished penthouse is a very exclusive property. The penthouse on the Main extends over three floors and is decorated extravagantly with the finest materials. Six bedrooms, five bathrooms and a spacious reception floor leave nothing to be desired. The different features at a glance: Floors: walnut plank floor, natural stone in bathrooms, tiles, hand-tufted carpets. I think best part of the house is the beautiful river view.
