Pietra Rara B&B is a great place to stay. The property is very stylish, comfortable, and clean, and Daniela provides a lovely continental breakfast in the mornings. Note that the breakfast is an extra 10 Euros per person per day. Also make sure you call or message Daniela in advance of your arrival to confirm check-in instructions, because if you arrive in the afternoon or evening there might not be anyone at the property to let you in, and the key will be hidden in a lockbox.
The B&B is in a beautiful location nestled in the mountains and vineyards near the Sarca River. We absolutely loved this part of Italy. It's very peaceful and relaxing and not crowded with tourists. A car is essential, but driving is easy and the roads are nice.
