I have stayed at many AirBnBs in Portugal over the past two years, but I can honestly say that Sissi's apartment was the best I have ever stayed in. The apartment feels more like a small house, with beautifully decorated rooms and high ceilings. Even on hot days, the apartment is naturally cool at night. The shower and kitchen appliances are completely new and state of the art. It was very easy to communicate with Tiago (Sissi's son) and Sissi. They left some nice welcome snacks for us upon our arrival, too. The neighborhood is one of the nicest in Lisbon while still being residential, with great restaurants, bakeries and gelato shops just down the street. The apartment is even lovelier in real life than in the photos, so I really recommend you rent this place to see for yourself!
