We had a wonderful experience at Giuseppe's property. At check-in, we were met by Marietta, who walked us to the apartment. She not only gave us a quick overview of the history of the neighborhood, but also gave us great tips on where to eat, what to see and how to take advantage of Lisbon's public transit.
Overall, the apartment was in great condition and had amazing views of the city and Tagus River. It's also centrally located, making it easy to walk to all of Lisbon's main tourist attractions.
One thing to note: Getting to the apartment requires a fair amount of stair climbing so pack accordingly.
