Too bad we did not meet Joana and Antonio (they were out of town), but they were very responsive to texts for the questions we had (like how to turn on the heat). Also, really glad they let us check in early!
The apartment was very nice. Comfortable bed. Kitchen stocked with coffee (+ percolator) and tea (+ electric kettle) when we were there. Quick tip for future winter guests: consider turning off the radiator when you sleep, as its clicking can be bothersome.
Location was awesome! Very central. Just a quick couple of blocks to the pedestrian areas of the Baixa. Supermarket just up the street.
