We staid one week at Joana's apartment in February and really enjoyed it. The apartment is extremely central, well equipped, nicely decorated and spacious. We came with a baby and Joana kindly provided us with a baby's cot and high-chair. The only little thing was that the heater in the bedroom became too hot at nights. But once we asked Joana, she has been really helpful and fast in giving us a solution.
We highly recommend Joana's apartment. We had great holidays in Lisbon.
