The location of the flat is excellent and Olga and Paulo are excellent hosts. Communication was excellent and always prompt. The flat is quite large and airy, although the stairs to the upstairs bedroom are very small and a bit treacherous. Heating on the lower floor is provided through a stove that runs on wooden pellets, which was a bit of a surprise in central Porto and the upstairs bedroom has an electric heater. You can’t really go for very long showers as the electric boiler that feeds both bathrooms and isn’t that big.
