Joao's flat is tiny but accomodating. Position is excellent, in the Alfama district very close to the Sao Jorge castle and its beautiful streets. The apartment only lacks in central heating, which I know most of the time in Lisbon is not needed, but in this period it got quite cold at night. Joao provides a heater, ours wasn't working properly and although we're sure Joao would have replaced it straight away we went for the cool air, blankets were warm enough. Stairs to flat are very steep, not a problem for us but could be for someone although visiting Lisbon you might as well get used to it. Overall I would recommend this flat for a short stay.
