The listing's pictures don't do the apartment justice - it's an amazing flat with an incredible view. It's close to restaurants, walking distance to the city centre and Castelo S. Jorge.
It is 2 stories by stairs and it can be a little hard to reach if you don't know the area, but other than that it's a great little gem that's very central to everything Lisbon has to offer.
Everything was clean, stocked up and we found it to be a very modern, welcoming home. I would highly recommend it and would pay the price mostly for it being so confortable and so central.
