We stayed for 8 days in the cottage on top of Monte Rosa and it was really great. The views are much better in real life than in pictures. It´s a cool feeling to be all alone on top of the mountain overlooking Stromboli, Vulcano and even Etna. Just you and the nature. The walk up to the house is a real workout and I recommend you to walk up some steep hills to get the feeling if you are staying more than a couple of days.
