This is a terrific apartment from which to experience the amazing city of Lisbon. Filipe was an excellent host - responsive, accommodating, friendly. The apartment was clean, modern, and cozy. It's a small space, but is perfectly suited for two people. The bed is comfortable.
The apartment is located in a terrific neighborhood that offers a taste of old world Lisbon. We really enjoyed wandering the streets of the Alfama. It's not terribly close to some of the city's main sites (Santa Justa Lift, Belem Tower), but that's hardly an issue. If you're not afraid of walking (or taking a bus or cab), you can get to just about anywhere (and explore Lisbon along the way).
The stairs leading up to the apartment are a bit steep, which can be tricky with luggage. But that's a small price to pay to stay in the charming place.
