The Nespresso Gran Maestria 520 Espresso Machine with Aeroccino Plus Milk Frother turns any kitchen into an Italian Sidewalk Coffee Café. This isn't just a package of 2 distinct machines, it is an integration of them through a special base that includes a unique hot water cup heater which injects a jet of hot water into your inverted espresso cup! Neat! The base also integrates the waste water from the cup heater into the drip tray, and the controls for the Aeroccino are mounted into the Maestria housing. So while the machines are separately recognizable as members of the Nespresso family, together in this platform they become so much more. Teamwork!
