Casa do Castelo is an immensely charming and quaint hotel/B&B - just like the proprietor himself.
In fact, Casa do Castelo is so charming, that it's few shortcomings seem like features, rather than shortcomings.
It is a perfect place if you want some peace and quiet, as the town of Atouguia da Baleia is very very docile; nothing happens, but in a good way...
At our holiday in Portugal we spent time in 5-star and 4-star hotels (7 in total), but we did not experience a better breakfast than the ones we had at Casa do Catelo: Good bread, good coffee, pastry, homemade jam, fresh orange juice and scrambled eggs. Very delicious.
Absolutely recommendable!
