Highly recommended. Beautifully finished, clean and exactly as described. The location is also perfect - in the heart of the Alfama district, and within walking distance of the main sights (the castle, praca do comercio). The apartment is also on the iconic tram 28 route (but no noise heard from traffic!).
Maria and Luigi were great hosts, helpful and flexible. If you plan to use the sofa bed, make sure you let them know in advance, so that they can provide the bedding.
