Here is a peek into the wonders of the Douro Hotel, the Casa do Arco by Douro Exclusive.The long-life dream of my excellent friends Marco and Ana, Casa do Arco is an intimate guest house for those who seek a more personal touch when staying in the Douro Valley.The house is perched atop a southern-facing hill, overlooking the Pinhão river, providing its guests a one-of-a-kind scenery for their stay.With 2 rooms and 1 suite, a fine dining restaurant, and a wine cellar brimming with local choices, you could not find a more attentive and personal hotel to stay in the Douro Valley.
