The apartment has great views and is in a vibrant spot, surrounded by great food and some small grocery stores. The space is very small, but cozy and efficient. Be aware if you're traveling in June that the neighborhood plays very loud music over the speakers until very late in the night, which is fine if you're a night owl, but not so good if you're trying to get to bed early. I think this music stops after the month of June is over. The flat is very close to the Santa Apolonia train station, and a 10-15 minute walk to Praça Commercio, a central part of the city. The neighborhood has a lot of tourists, but it is very close to many beautiful viewpoints and great walks that feel less crowded.
We never met Susana, but we spoke on the phone, and she gave us great, family friendly activity ideas. Susana's associate, Lúcia checked us in and also gave us great recommendations within the city. I love the old part of Lisbon, and overall we enjoyed staying at this flat.
