We had a lovely stay at Barbara and Tiago's place. It has a prime location for travellers that would like to skip public transport (although you have to brace yourself for the uphill slopes). The apartment has everything you need (especially if you want to cook) and the view is simply amazing. One tiny thing to note would be the heating: since the building does not have a heating system, it can get a bit chilly inside at night and early in the morning (if you're visiting in winter). The small heater inside the apartment may not be enough for those sensitive to the cold.
