It is already some years that i spend some time in Colle delle Querce in Todi, the place is beautiful, the view is fantastic. The "agriturismo" is just on the hill in front of Todi in the middle of nature, people can see the Todi and the Tevere river.
The owner is very friendly, it is like to be at home even because guests can take vegetables and fruits from the garden as much as they want.
Nearby, in the city of Todi is full of medium/small restaurants with the traditional cooking from the Umbria region.
I would recommend it to everybody who looks a nice place to relax ans be in contact with nature.
