The apartment is exactly as advertised. It's clean, cozy and central to some of Lisbon's most lively neighbourhoods. Graça was an absolutely wonderful host - she arranged a driver to collect us at the train station, provided us with a comprehensive overview of Lisbon and stocked the fridge with a few amenities to get us started for our stay. We couldn't have asked for anything more!
My one and only cautionary note: the ceilings are low in some areas of the apartment, tall people beware!
