This one is a no-brainer. The MXP Sheraton is one of the most convenient, delightful airport hotels that exist. It's virtually part of the terminal. It seems that many, many top tier international flight crews stay there. Just sitting in the lobby and watching them come in with their incredible uniforms and strong airline and national pride is amazing. The MXP Sheraton adds to your flight. You can also wake up a half hour later because the hotel is literally part of the airport. No need for a shuttle. I've stayed at both. Sheraton, hands down.
