We were a group of four staying at Portas Do Sol and the space was just enough. Our host was already there when we arrived and greeted us with a warm welcome. The apartment was impeccably clean, organized, and well styled. The location is amazing as well, great options for restaurants and bakeries. You'd also be a 10 walk from the oldest district, Alfama.
If you're coming to Lisbon, we highly recommend you consider Potas Do Sol.
