The Leadership in Energy and Environmental Design-certified Element by Westin, located 13 miles from the Las Vegas strip, hosted Obama Wednesday night, the Las Vegas Sun reported.
Obama's room was outfitted with in-room recycling bins for paper, plastic and glass, carpets made from recycled materials, and energy-efficient appliances and light bulbs.
The choice to stay at the environmentally friendly Element made sense, said David Smith, the hotel's general manager.
"I believe the topic of his time here was along those lines," he said of Obama's speech in Las Vegas that focused heavily on energy policy.
For dinner, Obama and his entourage ordered 20 cannolis and 12 pizzas from nearby Dom DeMarco's pizzeria.
Albert Scalleat, co-owner and general manager of the pizza shop, personally made the delivery to the hotel.
"It was almost like being in a movie," said Scalleat, 67.
The president's chef told Scalleat, "The president wanted me to tell you he loved the pizza and the cannolis," Scalleat said.
