João is a great host. Fast and friendly communcation. Appartment is clean an comfortable. 50 m from great viewpoint to the Lisbon from the top. Several nice restaurants is just across the street.
If you arrive to the place not by taxi, but by metro - be aware that huge staircase need to be passed. But this staircase is very-very cozy. 10 min walk to metro station, which brings yout to the city center very fast.
Appratment is higly recommeded for the Lisbon descovery as the balance of price/place/infrustructre/ appartment host.
