A relatively small hotel on a promontory between the Douro valley and a tributary valley.. Surrounded by hills, vineyards and small villages lodged on the very steep slopes. Porto Antigo is a very small hamlet,the hotel being the main economic activity. Thoroughly enjoyed our six day stay at the hotel following a week on a Douro river cruise. Our room had a fantastic view and veranda overlooking the lake formed by the dammed Douro river. Hotel was very clean & comfortable, buffet breakfasts were extremely good, fresh fruit & croissants, various cold meats / cheeses etc., help yourself to as much as you want. Restaurant for evening meals had a good choice of locally inspired dishes as well as good choice of local wines. Hotel gets much busier at the weekend when the locals take advantage of the small marina facilities for various water sports eg jet skis, water skiing, power boating etc. Small swimming pool between front of hotel and lake front clean and handy - given the foregoing much busier at weekend. Staff very friendly & extremely helpful with nothing too much trouble. We were looking for a quiet, relaxing few days in a picturesque lakeside location & that is exactly what we got. Would I book again - definitely.
