It's an old house in Alcantara as expected, old part of the city, but the inside is very well done with plenty of space. We were 6 adults and had no problems sharing the two full bathrooms. There's about half a mile walk to get to the train station which gives you access to downtown Lisbon. Taxis are just around the corner too. A few coffee places very close to the apartment.
Overall very satisfied with our stay.
