Tornoalago was one of 4 places we stayed on our two week honeymoon in Italy, and it was our favorite of all of them. The village of Torno is straight out of a storybook. It feels like a very special and very well-kept secret. It is a tiny place - the waterfront has exactly one bar/cafe and one restaurant. In the morning, everyone in town is having cappuccinos at one and in the evening everyone is having dinner at the other. It's quiet and relaxing but feels communal as well. At Tornoalago, Rainer and Cris are a traveler's dream. They clearly love what they do and it sets the mood of your stay. You can't help but enjoy yourself when you're hanging out with them, whether it's in their spectacular wine cave or just on the steps to your room. They are gracious and accommodating and lovely to be with. The rooms themselves are modern, clean and neat and have a designer's touch; Cris is an artist and textile designer and it shows.
One thing I would note if you stay here is that the village is tiny and there isn't much to do there during the day (in particular, there isn't really a great beach area) so you may want to plan daytime excursions or activities elsewhere. We spent one of the days on a long spectacular hike in the mountains (ask Rainer for tips) and another in Bellagio (too touristy for us) which you can reach by ferry. Then come back and have a drink in the awesome wine cave!
All in all, a wonderful experience with great people in a great place. You leave feeling lucky. :)
