We first visited Guarda in 1983 and have been back 9 times and have yet to see an American there. I'm not sure why but it is a dreamy village set on a terrace above the lower Engadin valley below. It has three hotels, each with its own vibe. Hotel Meisser was a solid three star hotel but in the last five years has added more deluxe accomodations and increased prices accordingly.
We now favor Pensiun Val Tuoi and stay in their Dachstudio. It's a large open beam room with kitchen bath and fantastic balcony overlooking the town and valley below. The cost of US$110 makes it a great value too.
Guarda is a hikers paradise and thats why we go but there is no nightlife at all so this needs to be considered. It is a working farm village and the cows and goats determine the pace of work. It is a historical site as it contains the best examples of the architecture famous in the Enadin know as "sgraffiti haus". These thick walled, multi storied houses have the cows in the bottom floor and the family living above. They capture the essence of Endadin farm life and are richly decorated in a plaster design.
Pensiun Val Tuoi includes a generous breakfast and offers a dinner each night with salad bar and typical Engadin meal.
If hiking and reading while listening to cow bells ring in the background is your thing then Guarda may be right for you. There are no shops, other than a Migros so stop off in Zurich first if you like to shop! There is an excellent Appenzell Biological Beer that tastes great out on the balcony watching the sunset. It's all about the mountains here.
