We had a fantastic stay overall at Nadia's place. The villa itself was superb - stylish, clean, wonderful views, calm, and well-provisioned. Between the great pool area and the backdrop of Lovere (which is in walkable distance to the town center), it made for a perfect summer holiday setting for us and our two young kids. Nadia was a great host as well - very friendly, responsive, and able to facilitate our stay with a lot of thoughtful touches.
As others have noted, some of the roads are a bit narrow getting up the final stretches to the villa. However, they are manageable given some care driving and definitely should not deter you from choosing the place.
We'd gladly stay again!
