I had a wonderful stay at Christel's place in the Alfama district. The apartment was clean and comfortable with a terrific view overlooking the rooftops and river, facing the sunset. A short walk to the famous Tram 28 line, also easily walkable to Praça do Comércio and not far from Santa Apolónia station. Lots of winding alleys to explore. Wear comfortable shoes for all the escadinhas!
