I stayed for 2 months and loved this place and village. The house is spacious with views that you can stare at all day. The location is perfect for many hikes, and day trips to surrounding towns and villages and there are beautiful walks around Navacepeda de Tormes itself. The house is well equipped and maintained and has everything you need. The owners were very responsive to any questions I had.
You definitely need a car as there are no shops available in the village. However Hoyos del Espino with many bars, restaurants and grocery stores is only 8kms away and Bar Rincon in the village is very welcoming.
