If you like a very quiet, rural place at an organic farm Quinta das Colmeias might be a tip for you. Pure! loved the idea of being surrounded by organic chickens and sheep.
The farmers grow organic vegetables and fruit in the garden. It’s a nice place for a morning walk to see the animals.
We stayed in the self catered cottage, which is furnitured in a classical way. Be aware of the hard matresses, you might need some extra pillows, at least I did ; ). quinta-das-colmeias.com
