Flat is clean and located in a very good location ( 3 min walk from the Ribiera) . The bed is comfortable and make your sleep tight :).
However, my main issue would be the fees for accessing the flat heater (even in December). I already raised my concern to Joao and believe if the flat is rented out everything in there should be free to use , without any hidden cost.
Lastly, Joao always responded to queries and concerns in a timely manner .
